Gasoline flows through an orifice flow meter of diameter 0.58 m which has a hole diameter of 0.28 m. the upstream pressure is 41.7 pa and the downstream pressure is 13.4 pa. the flow coefficient is given to be 4.8. compute the volumetric flow rate and mass flow rate of the flowmeter. the density is given as 917.15 kg/m^3

Acarnot refrigerator operates in a room in which the temperature is 21°c and of power when operating. if the food compartment of the refrigerator is consumes 3 kw to be maintained at 2°c, determine (a) the coefficient of performance of the cycle and (b) the rate of heat removal from the food compartment. refrigerator cycle that has a higher coefficient of performance than that of the discussed (e) is it possible to develop a carn ot refrigerator, operating between the same temperature limits? explain
