A vendor claims that an adiabatic air compressor takes in air at standard atmosphere conditions and delivers the air at 650 kPa (gage) and 285°C. Is this possible? Justify your answer by calculation. Sketch the process on a Ts diagram. Also, What is the lowest possible delivery temperature generated by an adiabatic air compressor, starting with standard atmosphere conditions and delivering the air at 650 kPa (gage)? Sketch the process on a Ts diagram.
A rectangular cavity consists of two parallel, 0.5-m- square plates separated by a distance of 50 mm, with the lateral boundaries insulated. The heated plate is maintained at 325 K and the cooled plate at 275 K. Esti- mate the heat flux between th..
