Worksheet provided by your instructor to document your answers. 1. A weight of 20,000 lb. is supported on a rectangular base plate that is 8 in. wide
and 3 ft long. The base plate rests on a concrete slab. Determine the stress that the
base plate exerts on the concrete slab. Express your answer in units of (a) lb/in.2
and (b) lb/ft? (precision of 1 for (a) and of 1000 for (b))

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
