A liquid of specific gravity 0.85 is flowing through in an inclined venturimeter of 250 mm x 115mm size. the difference of pressures between the main and throat is measured by a liquid of specific gravity 0.65 contained in an inverted U- tube which gives a reading of 275mm. If the loss of head between the main and throat is 0.3 times the Kinetic head of the pipe, determine the rate of flow of liquid
