Question $3$

Figure $3$ shows a pipe rig in a laboratory for testing different flow meters. A pressure meter is installed at the outlet of the pump and gives a reading in meter head of water. If the meter reading shows $5\mathrm{.}0$ m :

a$)$ Calculate the pressure at the pump outlet in $\frac{N}{m^2}.$

b$)$ Apply Bernoulli equation and determine the flow velocity at the pipe outlet and thus the discharge through the pipe.

c$)$ If the measuring tank is used to collect the water, calculate the volume of water collected in $60$ seconds.

Pipe diameter at pump outlet $($A$)$: : Pipe diameter at pipe rig outlet $($B$)$
