A large adiabatic compressor receives air from the ambient at 95 kPa, 20 deg C with negligible velocity. The air exits the compressor at 1.52 MPa, 430 deg C, and with a velocity of 90 m/sec. The power input to the compressor is 5000 kW. Find the mass flow rate of air through the compressor

An electric kettle is made out of stainless steel, weighs two pounds (when empty) and is equipped with a heating element that consumes 2 kw of electricity. assuming that the water and the kettle are at the same uniform temperature at any moment of time, calculate the shortest possible time to bring 2 quarts of water from room temperature to the onset of boiling
