Question
Water flows through a corner valve at a flow rate of Q=0.75 m³/s . The pressure just
upstream of the valve is P₁ = 500 kPa and the pressure just downstream is P₂ = 300 kPa. The
inside pipe diameters of the valve inlet and exit are respectively, D₁ = 5 cm and D₂ = 12 cm.
If the flow through the valve occurs in a horizontal plane, determine the head loss, h₂ (in
meters) and the rate of loss of available energy (in W) across the valve.
