The air velocity in the duct of a heating system is to be measured by a pitot-static probe inserted into the duct par- allel to the flow. if the differential height between the water columns connected to the two outlets of the probe is 2.4 cm determine (a) the flow velocity and (b) the pressure rise at the tip of the probe. the air temperature and pressure in the duct are 45°c and 98 kpa, respectively

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.
