The electronic components of a computer are cooled by air flowing through a fan mounted at the inlet of the electronics enclosure. At steady state, air enters at 20 °C, 1 atm. For noise control, the velocity of the entering air cannot exceed 1.3 m/s. For temperature control, the temperature of the air at the exit cannot exceed 32 °C. The electronic components and fan receive, respectively, 80 W and 18 W of electric power. Determine the smallest fan inlet diameter, in cm, for which the limits on the entering air velocity and exit air temperature are met.

A heat pump is used to maintain the interior of a building at 21 °C. At steady state, the heat pump receives energy by heat transfer from well water at 9°C and discharges energy by heat transfer to the building at a rate of 120000 kJ/h. Over a period of 14 days, an electric meter records that 1490 kW-h of electricity is provided to the heat pump. 1. Draw a schematic diagram(s)

A mixing vessel initially contains 3,936.2 lb of liquid fluid. The vessel is fitted with two inlet pipes, one delivering hot fluid at a mass flow rate of 0.216 Ib/sec and the other delivering cold fluid at a mass flow rate of 0.94 lb/sec. Fluid exits through a single pipe at a mass flow rate of 1.268 Ib/sec. Calculate the amount of fluid, in lb, in the tank after 24 minutes.
QI: At winter design conditions, a house is projected to lose heat at a rate of 65,000 Btu/h. The internal heat gain from people, lights, and appliances is estimated to be 6500 Btu/h. If this house is to be heated by electric resistance heaters, determine the required rated power of these heaters in kW to maintain the house at constant temperature.
