Calculate the mass flow rate for water spray tank shown for

Question

1. Calculate the mass flow rate for the water spray tank shown for the following given information:

h=0.8 m,
hose inside diameter : D=0.015 m
hose length: l =1.9 m
hose friction factor: f=0.11
hose inlet loss coefficient: K_in=0.8
nozzle exit diameter: d=0.0075 m
nozzle loss coefficient: K_nozzle=0.75
θ=40^o
P=150 Kpa (Gage)
