A steam trap with a 6-mm orifice in an 0.8-MPa steam system has failed open. The steam system is pressurized 8.760 hours/yr. The steam cost is $15.00 /GJ. Using the table below, what is the annual cost of the vented steam through the failed steam trap? ignore any condensate return issues.
[The question from the previous image, which was about calculating the annual cost of heat loss through a wall, but had a discrepancy between the calculated cost and the provided answer choices]
Correct Answer: C 🗳️
A 3 MW rated wind-powered turbine has a rotor diameter of 113 meters. What is the efficiency of the wind turbine at rated power if it is operating in wind power calculated at 8.6 MW? Assume an air density of 1.225 kg/m³.
Correct Answer: D 🗳️
The temperature in an unconditioned mechanical room is found to typically be around 23°C warmer than ambient (outside) air. If the air intake of an air compressor located in the mechanical room is routed through a nearby wall so that the cooler outside air is fed directly to the air compressor's intake, the compressor's energy requirement will now be expected to:

A facility has the thermal cooling load profile shown in the table below. The utility rate tariff has an on-peak time-of-use billing period that begins at 10:00 a.m. and ends at 7:00 p.m. Calculate the storage capacity required for a load-shifting operating strategy, to make sure that no thermal cooling Is generated by the chiller during the on-peak utility rate period.
