25 points The temperature of the earth's atmosphere varies according to the equation T=-0.0052 + 288.15 where T is in Kelvin and z is in meters. If the air temperature at ground level is is °C and pressure is 760 mm Hg. Assume air to be an ideal gas with an average molecular weight of 28.9 g/mol. At an elevation of 5,575 m what is the corresponding pressure in mm Hg? 0 380 0 280 480 O 880

An air conditioning system consist of a 5 cm diameter pipe, operating at a pressure of 200 kpa. the air initially enters the pipe at 15°c with a velocity of 20 m/s and relative humidity of 80%. if the heat supply throughout the process is 960 w, determine the relative humidity and the temperature at the outlet

The thermal expansion or contraction of a given metal is a function of the f a)-density b)-initial temperature c)- temperature difference d)- linear coefficient of thermal expansion e)- final temperature f)- original length

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
