Quiz2: Air enters a chamber at 10°C dry-bulb temperature (DBT) and 5°C wet-bulbtemperature (WBT) at a flow rate of 100 m³/min, with the barometric pressure at 101.325 kPa.As it passes through the chamber, the air absorbs sensible heat at a rate of 40 kW and picksup 45 kg/hr of saturated steam at 105°C. Determine the dry-bulb and wet-bulb temperaturesof the air as it leaves the chamber. Additionally, determine the condition of the air between theheater and the humidifier. Finally, explain how you would estimate the humidifier efficiency.

To solve the problem, we need to follow these steps: 1. Determine Initial Conditions: • Dry-bulb…

Steam expands adiabatically in a nozzle from inlet conditions of 130(psia), 420(°F),and a velocity of 230(ft)(s)−1 to a discharge pressure of 35(psia) where its velocity is2000(ft)(s)−1. What is the state of the steam at the nozzle exit, and what is SG for theprocess?
A nozzle is a device for increasing the velocity of a steadily flowing fluid. At the inlet to a certain nozzle the specific enthalpy of the fluid is 3045 kJ/kg and the velocity is 70 m/s. At the exit from the nozzle specific enthalpy is 2850 kJ/kg. The nozzle is horizontal and there is a negligible heat loss from it. Determine; e. 1. The velocity of the fluid at exit The rate of flow of fluid when the inlet area is 0.1 m? and the specific volume at inlet is 0.19 m/kg. ii. The exit area of the nozzle when the specific volume at the nozzle exit is 0.5 m'/kg. 11.
Problem 2. Consider a Variable Air Volume (VAV) system, which serves for two rooms. The air temperature at the exist of the cooling coil is 10 °C. The design room temperature is 24 °C for both rooms. For room 1, the sensible and latent heat load is 60 and 10 kW, respectively. For room 2, the sensible and latent heat load is 40 and 10 kW, respectively. Determine (1) The mass flow rate for each room in kg/s; (2) The actual relative humidity of each room.
0.2 A condenser condenses 2700kg steam per hour while air leaks into It at 2.2kg/hr. The condensate and air suction spout temperatures are 32.9°C. The barometer and vacuum gauge readings are 765mmHg and 690mmHg respectively. The condenser uses 125.55M9 of cooling water per hour to condense steam with a dryness fraction of 0.86 and the air pump has a volumetric efficiency of 82.5%. Take R = 0.287kJ/kgK for air and calculate: %3D 6.2.1 the temperature rise of the cooling water (10.85°C); 6.2.2 the air pump capacity in m2/min (0.78m3³/min).

Question No. 1a) A rigid tank containing 0.4m3 of air at 400 kPa and 30oC is connected by a valve to a piston cylinder device with zero clearance. The mass of the piston is such that a pressure of 200 kPa is required to raise the piston. The valve is opened slightly and air is allowed to flow into the cylinder until the pressure of the tank drops to 200 kPa. During this process, heat is exchanged with the surrounding such that the entire air remains at 30oC at all times. Determine the heat transfer for this process.

ASEM 12/6/2015 Q1/ A stream of warm water is produced in a steady flow mixing process by combining 1.0 kg/s of cool water at 25 °C with 0.8 kg/s of hot water at 75 °C. During mixing, heat is lost to the surroundings at the rate of 30 kJ/s. What is the temperature of the warm water stream? Assume the specific heat of water constant at 4.18 kJ/kg.K.
Problem 2 A diffuser is a device designed to decrease the velocity of a steadily flowing stream while increasing its pressure. At the inlet to a certain diffuser, the enthalpy of the fluid is 276 kJ/kg and the velocity is 250 m/s. At the discharge end, the enthalpy is 300 kJ/kg. The diffuser is horizontal and there is zero heat loss from it. (Be careful about units!) (a) Calculate the velocity at the exit of the diffuser.
