Question

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?)

A large tank (left side), filled with pressurized water, fills another large tank (right
side) open to atmosphere. Originally, the valve is shut, causing the pipe upstream of
the valve to be flooded with water, and the pipe and tank downstream of the valve
to be flooded with air. The diameters of the tanks are very large relative to the
diameter of the pipe. When opened, the valve offers negligible resistance to flow.
Use the Bernoulli Equation to solve the following problems.
