An air conditioning unit has a cooling coil that cools and dehumidifies 10,000 cfm of air from 90°f db and 65% rh to 65°f db and 50% rh. the amount of moisture condensed in the cooling coil is approximately: (a)-601 lb/hr (b)-501 lb/hr (c)-401 lb/hr (d)-301 lb/hr

Thermal stresses are developed in a metal when its a) initial temperature is changed b) final temperature is changed c) density is changed d) thermal deformation is prevented e) expansion is prevented f) contraction is prevented

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

Which of the following refers to refers to how well the control system responds to sudden changes in the system. a)-transient regulation b)- distributed regulation c)-constant regulation d)-steady-state regulation
