A classroom that normally contains 40 people is to be air-conditioned with window airconditioning units of 5-kW cooling capacity. A person at rest may be assumed to dissipate heat at a rate of about 360 kJ/h.

The pressure gauge on the steam condenser for a turbine indicates 66.5 mm Hg of vacuum. The barometer reading for the local atmospheric pressure is 755 mm Hg. What is the pressure in the condenser in psia g

How can you relate entropy to renewable and non-renewable energy?

igure P4.57 provides steady-state operating data for a parallel flow heat exchanger in which there are separate streams of air and water. Each stream experiences no significant change in pressure.

The ladder has a uniform weight of 80 lb and rests against the smooth wall at B. If the coefficient of static friction at A is mu (a) = 0.4, determine if the ladder will slip.

Just getting to your class is enough for showing up. A) True B) False

A completely reversible heat pump produces heat at a rate of 100 kW to warm a house maintained at 25℃. The exterior air, which is at 0℃, serves as the source.

A closed system undergoes a process in which work is done on the system and the heat transfer Q occurs only at temperature Tb. For each case, determine whether the entropy change of the system is positive, negative, zero, or indeterminate.

A scientist who is evaluating an ancient human skeleton for signs of vitamin and nutrient deficiency is conducting:
