In an air standard diesel cycle, the compression ratio is 15, and at the beginning of isentropic compression, the temperature is 27°c and the pressure is 0.1 mpa. heat is added until the temperature at the end of the constant pressure processis 1450°c. for air, take cp1.005 kj/kg k and c, 0.718 kj/ kg k. calculate (a) the cut-off ratio. (b) the heat supplied per kg of air. (c) the cycle efficiency. (d) the mean effective pressure in kpa.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
