Figure 3 shows a 250mm diameter pipe is placed in an inclined position where a venturimeter of 150mm throat is inserted. The difference of pressure between the main and the throat is measured by a liquid of specific gravity of 0.67 in an inverted u tube which gives a reading Of 275mm. If the loss of head between the main and the throat is 0.3 times the kinetic head of the pipe, find the discharge of water flowing in the 250mm pipe.
