Consider a low-speed open-circuit subsonic wind tunnel. the tunnel is turned on, and the pressure difference between the inlet (the settling chamber) and the test section is read as a height difference of 10 cm on a u-tube mercury manometer. (the density of liquid mercury is 1.36 x 104 kg/m3.) assume that a pitot tube is inserted into the test-section flow of the wind tunnel. the tunnel test section is completely sealed from the outside ambient pressure. calculate the total pressure measured by the pitot tube, assuming the static pressure at the tunnel inlet is atmospheric. (round the final answer to two decimal places.) the total pressure measured by the pitot tube is * 105 n/m2

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.

Acertain flow of air (at stp) has a velocity distribution given by v i (in ft/s). if this flow is going through a 4 ft square area in the yz-plane (centered at the origin), what is the mass flow rate (in lbm/s)?
