A thermal storage tank holds 500 gallons of ethylene-glycol mixture (V =1.9 m^3, p=850 kg/m^3,Cp= 3500 J/(kg: °C) and experiences an 10°C temperature rise during the course of one sunny day. How much energy (kj) was taken from the solar collector that day?

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

An air conditioning system consist of a 5 cm diameter pipe, operating at a pressure of 200 kpa. the air initially enters the pipe at 15°c with a velocity of 20 m/s and relative humidity of 80%. if the heat supply throughout the process is 960 w, determine the relative humidity and the temperature at the outlet
