As shown, a load of mass 10 kg is situated on a piston of diameter D1 = 140 mm. The piston rides on a reservoir of oil of depth h1 = 42 mm and specific gravity S = 0.8. The reservoir is connected to a round tube of diameter D2 = 5 mm and oil rises in the tube to height h2. Find h2. Assume the oil in the tube is open to atmosphere and neglect the mass of the piston.

A power cycle operating at steady state receives energy by heat transfer at a rate Q˙ H at TH = 1500 K and rejects energy by heat transfer to a cold reservoir at a rate Q˙ C at TC = 500 K. For each of the following cases, determine whether the cycle operates reversibly, irreversibly, or is impossible. If it is impossible, state why it is impossible. (a) Q˙ H = 550 kW, Q˙ C = 100 kW (b) Q˙ H = 500 kW, W˙ cyc = 200 kW, Q˙ C = 200 kW (c) W˙ cyc = 300 kW, Q˙ C = 150 kW (d) Q˙ H = 500 kW, Q˙ C = 200 kW

An exercise room has six weight-lifting machines that have no motors and seven treadmills, each equipped with a 2.5-hp (shaft output) motor. The motors operate at an average load factor of 0.7, at which their efficiency is 0.77. During peak evening hours, all 13 pieces of exercising equipment are used continuously, and there are also two people doing light exercises while waiting in line for one piece of the equipment. Assuming the average rate of heat dissipation from people in an exercise room is 740 W, determine the rate of heat gain of the exercise room from people and the equipment at peak load conditions.
