Two water reservoirs A and B are connected to each other through a 40-m-long, 2-cm-diameter cast iron (ε = 0.00026 m) pipe with a sharp-edged entrance (K₁ = 0.5). The pipe
also involves a swing check valve (K₁ = 2), a fully open gate valve (K₁ = 0.2) and the exit (K₁ = 1). The water level in both reservoirs is the same, but reservoir A is pressurised by
compressed air while reservoir B is open to the atmosphere at 89 kPa. The initial flow rate through the pipe is 1.2 litre/s and the water temperature is 10°C (p = 999.7 kg/m³, µ =
1.307 x 10³ kg/ms).
