Chapter 6, Problem 32P
A jet of air from a nozzle is blown at right angles against a wall in which two pressure taps are located. A manometer connected to the tap directly in front of the jet shows a head of 25 mm of mercury above atmospheric. Determine the approximate speed of the air leaving the nozzle if it is at −10°C and 200 kPa. At the second tap a manometer indicates a head of 5 mm of mercury above atmospheric; what is the approximate speed of the air there?

Assume the water in the first tank maintains its height and pressure. The valve is opened and after a while a pressure gauge located at the valve reads an absolute static pressure of 190kPa. At this instant the height of the water in tank 2 is 8.2m relative to its base. Take the height of the valve to be 8m. What is the mass flow rate through the pipe? (HINT: What is the practical velocity of the fluid in the tanks if they are very large?)
