Q.1 Water is flowing through a pipe of 5 cm diameter ander a pressure of 29.43 N/cm²(gauge) and with mean velocity of 2.0 m/s. Find the total head or total energy per unit weight of the water at a cross-section, which is 5m above the datum line. Q.2 A pipe, through which water is flowing is having diameter, 20 cm and 10 cm at the cross-sections 1 and 2 respectively. The velocity of water at section 1 is given 4.0 m/s. Find the velocity head at sections 1 and 2 and also rate of discharge. Q.3 The water is flowing through a pipe having diemeters 20 cm and 10 cm at sections 1 and 2 respectively. The rate of flow through pipe is 35 litres/s. The seçtion 1 is 6 m above datum and section 2 is 4 ft above datum. If the pressure af section 1 is 39.24 N/cm², find the intensity of pressure at section 2. Q.4 Water in flower through a pipe having diameter 300 mm and 200 mm at the bottom and upper end respectively. The intensity of pressure at the bottom end is 24.525 N/cm² and the pressure at the upper end is 9.81 N/cm² to Determine the difference in datum head if the rate of flow through pipe is 40 lit/sec. Q.5 An oil of sp.gr. 0.8 is flowing through a venturimeter having inlet diameter 20 cm and throat diameter 10 cm. The oil-mercury differential manometer show a reading of 25 cm. Calculate the discharge of oil through the horizontal venturimeter. Take Cd = 0.98
