Outside air at 50°f, 1 atm, and 40% relative humidity enters an air-conditioning device operating at steady state. liquid water is injected at 45°f and a moist air stream exits with a volumetric flow rate of 1000 ft3/min at 90°f, 1 atm and a relative humidity of 40%. neglecting kinetic and potential energy effects, determine a. the rate water is injected, in lb/min.

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.1 m below the tank bottom which is a = 7.4 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute)

In which of the following would the particles move most rapidly? a. ice at -20 °c b. water at 20 °c c. steam at 110 °c d. boiling water e. ice at 0 °c

While the change in blank will remain the same during a collision, the force needed to bring an object to a stop can be blank if the time if collision is blank
