The answer is there but the method was confusing
7B.4 Flow between two tanks. Case 1: A fluid flows between two tanks A and B because Pa > PB. The tanks are at the same elevation and there is no pump in the line. The connecting line has a cross-sectional area S, and the mass rate of flow is w for a pressure drop of (PA -Ps(see Fig. 7B.4). Case I1: It is desired to replace the connecting line by...

A converging elbow turns water through an angle of 60° in a horizontal plane. The flow cross-sectional diameter is d1-200mm at the elbow inlet, and d2-100mm at the outlet. The elbow flow passage volume is 0.02m3 between sections (1) and (2). The water volumetric flow rate is 40 Liters/s and the pressure measured at the inlet is 150 kPa. Neglecting the weight of the elbow, calculate: a- The...
