A water pumping system is being driven by a propeller type wind turbine having the power coefficient of 0.4. The total pumping head and rate of discharge are 20 m and 7.0 L s^-1, respectively. Mean wind velocity is 18 km h^-1 and the density of air i1 AnswerThe term ‘Working head’ in context of water supply system means, GATE- Architecture and Planning- 2013 1 AnswerA calorically perfect gas (specific heat at constant pressure 1000 J/kg.K) enters and leaves a gas turbine with the same velocity. The temperatures of the gas at turbine entry and exit are 1100 K and 400 K, respectively. The power produced is 4.6 MW and heat escapes at the rate of 300 kJ/s through the turbine casing. The mass flow rate of the gas (in kg/s) through the turbine is1 AnswerWhich one of the following is favor able for an airplane operation?
