Modular masonry units are based on a module size and are reduced by the thickness of a standard mortar joint which is:
5/8", 1/2", 3/8", 1/4"
Answers
The standard thickness of a mortar joint for modular masonry units is typically 3/8".
Modular masonry units are designed with a module size, which is a standardized dimension used in construction. This module size takes into account the thickness of mortar joints, which are essential for bonding the masonry units together. For modular masonry units, the standard thickness for mortar joints is generally 3/8". This thickness ensures proper alignment and uniformity in the masonry structure while providing a balance between structural integrity and efficient material usage. However, it's important to note that other thicknesses, such as 5/8", 1/2", or 1/4", may be used in specific construction scenarios based on design requirements and local building codes.

b)
∴ Amount of lost work is 79.589.37 kJ
Air is contained inside a vertical piston-cylinder assembly by a piston of mass 105 kg and face area of 0.05 m2 . The mass of air inside the cylinder is 20 grams, and the air initially occupies a volume of 50 liters. The atmosphere exerts a pressure of 101.3 kPa on the top of the piston. The volume of the air slowly decreases to 0.005 m3 , while maintaining constant pressure, as the specific internal energy of the air decreases by 175 kJ/kg. Neglecting friction between the piston and the cylinder wall, determine the heat between the surroundings and the air inside the piston-cylinder assembly in kJ
Answers
Answer:
ΔQ = 1.06 KJ
Explanation:
The amount of heat transfer between the piston-cylinder system and the surrounding can easily be found by using the First Law of Thermodynamics. The first law of thermodynamics can be written as follows:
ΔQ = ΔU + W
ΔQ = mΔu + PΔV
where,
ΔQ = Heat transfer between system and surrounding = ?
Δu = specific change in internal energy of the system = - 175 KJ/kg
m = mass of air = 20 g = 0.02 kg
P = Constant Pressure = 101.3 KPa
ΔV = Change in Volume = 0.05 m³ - 0.005 m³ = 0.045 m³
Therefore,
ΔQ = (0.02 kg)(-175 KJ/kg) + (101.3 KPa)(0.045 m³)
ΔQ = -3.5 KJ + 4.56 KJ
ΔQ = 1.06 KJ
Liquid water at 20°C is heated in a chamber by mixing it with saturated steam. Liquid water enters the chamber at the steam pressure at a rate of 4.6 kg/s and the saturated steam enters at a rate of 0.19 kg/s. The mixture leaves the mixing chamber as a liquid at 45°C. If the surroundings are at 20°C, determine:
a. the temperature of saturated steam entering the chamber,
b. the exergy destruction during this mixing process,
c. the second-law efficiency of the mixing chamber.
Answers
a. The temperature of saturated steam entering the chamber can be found by using the steam tables. At the pressure of the steam entering the chamber, which is not given in the problem, the saturation temperature is slightly above 100°C. Since the mixture leaves the chamber as a liquid at 45°C, we can assume that the steam is also at 45°C, which is the final temperature of the mixture. Therefore, the temperature of the saturated steam entering the chamber is 45°C.
b. The exergy destruction during this mixing process can be calculated as the difference between the inlet exergy and the outlet exergy of the system. The inlet exergy can be calculated as the sum of the exergy of the liquid water and the exergy of the saturated steam, which are both at the same temperature of 45°C. The outlet exergy can be calculated as the exergy of the liquid water at 45°C, assuming that there is no exergy transfer to the surroundings. The exergy destruction is then:
ΔE = (m_water * e_water + m_steam * e_steam) - m_outlet * e_outlet
where m_water and m_steam are the mass flow rates of the liquid water and saturated steam, respectively, and e_water, e_steam, and e_outlet are the specific exergies of the liquid water, saturated steam, and outlet liquid water, respectively.
Using the steam tables, we can find that the specific exergies of the liquid water and saturated steam at 45°C are 199.23 kJ/kg and 2513.9 kJ/kg, respectively. Therefore, the exergy destruction is:
ΔE = (4.6 kg/s * 199.23 kJ/kg + 0.19 kg/s * 2513.9 kJ/kg) - 4.79 kg/s * 199.23 kJ/kg
ΔE = 6253.7 kW
c. The second-law efficiency of the mixing chamber can be defined as the ratio of the actual work output (which is zero in this case) to the maximum possible work output, which is the inlet exergy minus the exergy destruction. Therefore, the second-law efficiency is:
η_II = 0 / (m_water * e_water + m_steam * e_steam - ΔE)
η_II = 0 / (4.6 kg/s * 199.23 kJ/kg + 0.19 kg/s * 2513.9 kJ/kg - 6253.7 kW)
η_II = 0
This means that the mixing process is not reversible, and there is no useful work output.

In a water jet macning, the mass flow rate of water is found to be 0.05 kg/s. consider water density as 996 kg/m and 0.02 cm is the diameter of the hole from which water jet comes out. neglect all the losses and potential head differences. determine the minimum pressure at which water suppling pump must operate.
Answers
The minimum pressure at which the water-supplying pump must operate is approximately 2.45 x 10⁶ Pa or 2450 bar.
Solution:To calculate the minimum pressure at which the water-supplying pump must operate, we need to use the formula for the volumetric flow rate of a fluid:
Q = A * v
where,
Q =the flow rate
A = the cross-sectional area of the hole
v = the velocity of the fluid.
We can use this formula to determine the velocity of the water, and then use the Bernoulli equation to determine the minimum pressure.
From the question:
ṁ=0.05 kg/s
ρ= 996 kg/m
d= 0.02 cm
Calculating the area of the hole:
A = (π/4) * (d²)
where,
d is the diameter of the hole, and pi is approximately 3.14.
d = 0.02 cm = 0.0002 m
A = (3.14/4) * (0.0002 m)² = 1.57 x 10⁻⁷ m²
Using the mass flow rate to calculate the velocity of water:
Q = ṁ / ρ
where,
Q = the volumetric flow rate
ṁ = the mass flow rate
ρ = the density of water.
Q = (0.05 kg/s) / (996 kg/m³)
Q = 5 x 10⁻⁵ m³/s
Using the area of the hole to find the velocity of water
v = Q / A
v = (5 x 10⁻⁵ m³/s) / (1.57 x 10⁻⁷m²)
v = 318.8 m/s
Using the Bernoulli equation to find the pressure:
P = Patm + (1/2) * ρ * v²
where,
P = the pressure
Patm = the atmospheric pressure
ρ =the density of water
v = the velocity of the water.
P = Patm + (1/2) * (996 kg/m³) * (318.8 m/s)²
Hence, the minimum pressure at which the water-supplying pump must operate is approximately 2.45 x 10⁶ Pa or 2450 bar.

To divide a clock by 8 with a duty cycle of 1/8th, use six T flip-flops and standard gates.
Can a clock be divided by 8 with a 1/8th duty cycle using T flip-flops and standard gates?To divide a clock signal by 8 with a duty cycle of 1/8th, we can use a combination of T flip-flops and standard gates. A T flip-flop is a type of sequential logic circuit that toggles its output based on the state of its inputs and a clock signal. By cascading six T flip-flops together, we can achieve a division factor of 2^6, which is equal to 64. However, we only need a division factor of 8, so we need to modify the circuit to achieve the desired output.
To obtain a duty cycle of 1/8th, we need to ensure that the output signal remains high for one-eighth of the period and low for the remaining seven-eighths. This can be achieved by using additional logic gates to manipulate the outputs of the T flip-flops. By carefully designing the circuit using standard gates such as AND, OR, and NOT gates, we can generate the desired output waveform with the desired duty cycle.
