25,000 cfm of outdoor air is brought into an HVAC system air handling unit (AHU). The air is at 100° F and 30% relative humidity, and is cooled down to 55°F and 80% relative humidity. a) What is the change in enthalpy between the incoming and supply air? b) What is the mass flow rate of the air being conditioned? b) What is the total cooling provided to this air flow in "tons of cooling"? c) How much moisture is condensed out of the air, in gallons per hour?

An air conditioning system takes 5000 cfm of moist air at 30°F, 40% relative humidity (state #1) and conditions it to 75°F, 40% relative humidity (state #2). a) How much water (Ibm/hr) is added to the air stream through the humidifier? b) What is the heat transfer at the heating coil (Btu/hr)? Patm 1 Humidifier Heating Coil 2.
Hi please show working? Thankyou ! An air conditioner cools humid air Temperature 1 =25 celcius Temperature 2 = 10 celcius Relative humidity 1 = 70% Determine the final relative humidity (2) and calculate: 1) the energy removed 2) the water mass extracted from the air
The following air streams mix in a building’s HVAC system upstream of the HVAC heating unit: 1,600 CFM outdoor air at 35°F and 70% RH mixes with 3,500 CFM of return air at 70°F and 40% RH. Assume the HVAC runs for 1 minute, so CFM is the same as cubic feet. a) What are the temperature and RH of the combined air stream? b) How much energy (units of BTU) does the HVAC heating unit need to add to the combined air stream to condition it to 80°F and 60% RH? c) If the conditioned air stream from the heating unit then mixes with 28,000 CFM of air at 70°F and 40% RH provided to the building from another source, what are the combined temperature and RH of the air in the building?

No card B a m OO ON 94)| 1:50 mlms.hu.edu.jo/mod/qu 3 A 476 m rigid tank contains saturated Refrigerant-134a mixture at 700 kPa with 27% quality. A valve at the bottom of the tank is now opened, and only liquid is withdrawn from the tank. Heat is transferred to the refrigerant such that the pressure inside the tank remains constant. The valve is closed when no liquid is left in the tank and vapor starts to come out. What is the amount of R-134a that exited from the tank "kg"? R-134a Sat. vapor P = 700 kPa Sat.
