Pressure used to be measured in units of 'inches of mercury' (in. Hg). The pressure was the hydrostatic pressure due to the number of inches of mercury. Atmospheric pressure is 2,116 psf and the specific gravity of mercury is 13.6. What is this pressure expressed in inches of mercury?

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.

For a gate width of 2 m into the paper, determine the force required to hold the gate abc at its location.

Consider airflow over a flat plate of length l = 1.5 m under conditions for which transition occurs at le = 0.9 m based on the critical reynolds number, re, e = 5 x 10. evaluating the thermophysical properties of air at 400 k, determine the air velocity. (hint: use the tables to find the properties of air)
