According to Dalton's law of partial pressures, the partial pressure exerted by the water vapor in a mixture of air and water vapor is equal to the pressure the water vapor would exert if it alone occupied the total volume of the mixture. If 1.00 m3 of humid air at 20.0°C contains 10.3 g of water vapor, determine
a. The partial pressure of the water vapor.
b. The maximum partial pressure of water vapor at this temperature.
c. The ratio of the answer in part a to that of part b (this ratio is called the relative humidity of the air). .
in a dual cycle the heat added at constant volume is equal to the heat added at constant pressure. the compression
A 400-mm-diameter impeller of a radial-flow water pump rotates at 120rad/s and has a discharge of 0.5 m3/s. Determine the discharge for a similar pump that has an impeller diameter of 100mm and operates at 90rad/s.
A converging nozzle with an exit diameter of 6 cm is attached to a reservoir maintained at 30-C and 150 kPa absolute. Determine the mass ?ux of air ?owing through the nozzle if the receiver exits to the atmosphere.
