A 98% efficient ESP is to treat a gas stream flowing at 5000 m3/ min. The effective drift velocity is 6.0 cm/s, each plate is 6 m by 10 m, and there are 3 mechanical fields. Assuming that each mechanical field has equal number of plates, what is: a) the plate area (required and actual) and b) the total required number of plates?

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.

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
