nlet and throat diameters of a horizontal venturimeter are 280 mm and 100 mm respectively. The liquid flowing through the venturimeter is water. Pressure intensity at inlet is 15 N/cm2, while  pressure at throat is 50 kPa. Find flow rate of water in lit/min, assuming Cd is 0.7 and also draw the neat sketch.     i) Actual flow rate = _______________________ lit/min.

Use g=32.2 */sec2 (9.81 m/s2) and 60°F (16°C) water unless told to do otherwise.• Google schedule-40 pipe’s thickness at different nominal size to obtain the innerdiameter of the pipe for accurate determinaLon of flow velocity.• Must show your work to support your selecLon. 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? (A) 3.2 */sec (1 m/s); from A to B(B) 25 */sec (7.0 m/s); from A to B(C) 3.2 */sec (1 m/s); from B to A(D) 25 */sec (7.5 m/s); from A to B
