Calculate the temperature and relative humidity, Chemical Engineering

Assignment Help:

In a drying system, 600 m3/min of ambient air at 20° C and 50% relative humidity is heated to a temperature of 50°C before passing into the drying chamber.

a) What are the specific volume, mass flow rate, absolute humidity and specific enthalpy of the air before it is heated?

b) What is the absolute humidity and specific enthalpy of the air after heating?

c) If the air is heated using an electric element, how many kW of power would be required (ignore heat losses)?

d) The air exits the dryer at a temperature of 30°C. Assuming adiabatic cooling, what is the absolute humidity of the air exiting from the drying chamber?

e) How many kilograms of water are removed from the product per hour?

f) If 200 kg/min of air with a dry bulb temperature of 35°C and a wet bulb temperature of 24°C was mixed with 400 kg/min of air with a dry bulb temperature of 15°C and a dew point of 7°C, what would be the temperature and relative humidity of the resulting mixture?
