Outside cool air at 15C and 40% relative humidity is mixed with inside air taken near the celling in a room at 32C and 70% relative humidity. Determine the relative humidity and temperature of the resultant air stream if the outside flow rate is 40 m^3/min and the inside flow rate is 20. m^3/min.
The process and volume relation is given p=(8-4v)bar for a non flow process ,where V is in cubic meter.If 130kJ of work is supplied to the system,calculate the final pressure and volume of the system.Take the initial volume as 0.5 cubic meter.
