Assuming the clearance is negligible for a single stage compressor with the following data : Atmospheric pressure = 90 kPa, Atmospheric temperature = 17 degrees, Delivery pressure = 7 bar, Free air delivery flow rate = 0,2 m³/min. Take n= 1,3, Cp=1,005 KJ/Kg K, Cv=0,718 KJ/Kg K
Determine the following :
A) Which formula is used to evaluate the delivery temperature for an isentropic?
B) the delivery temperature of air for a polytropic compression process with n=1,25 in Kelvin to 1 decimal place?
C) the mass flow rate of air inside the compressor operating isentropically in kg/min to 3 decimal places?
D) the power input to the compressor in kW to 2 decimal places if the compression is polytropic compression process with n=1,25?
E) the power input to the compressor in kW to 3 decimal places if the compression reversible isothermal?
