Otherwise, no points will be given.Water flows through a schedule-40 pipe that changes gradually in diameter from 6 in (154mm) at point A to 18 in (429 mm) at point B. The volumetric flow rate is 5.0 *3/sec (130 L/s). The respecLve pressures at points A and B are 10 psia (70 kPa) and 7 psia (48.3 kPa). All lossesare insignificant. What are the direcLon of flow and velocity at point A?

The point at which the upward water is discharged is in the atmosphere at a height of 5 m from the surface of the water storage tank. Calculate the friction loss during transportation [J/kg] when the inner diameter of the transport pipe is 50mm, the efficiency of the pump is 50% and the pump work (Wp) is 150J/kg (=m2/s2). However, it is assumed that the area of the liquid level of the water storage tank is very large compared to the cross-sectional area of the transport pipe outlet.arrow_forwardhandwritten pleasearrow_forward
