A air Compressor lequires a power input Of1400 kW andk It operates adialatically. The air is compressed from 300 K and atmospheric presšure to an exit pressure Of 20 atm, and the air leaves the comp ressor at a speed of 200 mlsec Assume that the air is an ideal gas and the inlet velocity is negligibly small, but do not ašsume that the specific ñeats are constant. if the mass flow rate is 2 kg/sec, calculate the air temperature at the exit in °C using 5 sgnifigan fiaures

Pls. Answer this..? A steam engine has 10% brake thermal efficiency and consumes 750 kg/hr steam. The enthalpy of steam at the entrance ang exit of the engine and condenser are 2800 and 450 kj/kg repectively. Determine the brake power of the engine in kw.

Please only answer STEP 2 question. THIS IS MY 3RD TIME POSTING THE SAME QUESTION AND NOT GETTING THE ANSWER I NEED. DONT SOLVE FOR THE MAIN QUESTION, I NEED THE ANSWER TO THE SECOND PART OF THE QUESTION.

A gas with flow rate of 100 MMSCFD of needs to be compressed from 800 to 8,000 psia. The inlet temperature is 90°F. How many stages are needed to compress the gas? Assume a 3% pressure loss between stages. Calculate the required HP. What type of compressor would you recommend? Assume n, = 0.9, and Em = 0.9. Yg = 0.62, k = 1.32.

Explain the steps in simple way so that i can understand the problem. Kindly don't use Ai ,It is Important one.

A single-stage single acting air compressor takes air in at 1 bar & delivers at 7.5 bar. Work done by the compressor is 38 kJ and the compressor runs at 150 rpm. Calculate the power required in kW/?     the power required in kW?

Ao air turbine with one intet and one exit operates at Steady State, and has heat trans fer to the Surroundings at an average 3.0x' 10" J per ka of air flowing. The inlet conditions are 980°K and 400 kPa, and the exit conditions are 670°k and 100 kla. Neglect kinetic and potential energy e ffects and use the ideal gas madel without assumung constant specific heats, to calculate the entropy producHon per mass of air flowing. Pres ent your answer in kJ/ (kgʻk) wsing 5 Signifigant figures. outer surface temperature of 315°k ät the rate of

A single acting reciprocating compressor is needed to compress 50 kg of air per hour from 100kPa and 25 C intake condition to 900 kPa delivering pressure. The compression is expected to follow PV to the 1.25 power = c. If the compressor has clearance factor of 4%and its expected to operate at 300 rpm, what is the require piston displacement.
