A pipe carrying water tapers from a cross-section of 0.3 m² at A to 0.15 m² at B, which is 6 m above the level of A. At A the velocity, assumed uniform, is 1.8 m s and the pressure 117 kPa gauge. If frictional effects are negligible, determine the pressure at В.

Water flows steadily through a horizontal 30 degree pipe bend. At the inlet point 1, the diameter is 0.3 m, the velocity is 12 m/s, and the pressure is 128 kPa gauge. At the outlet point 2, the diameter is 0.38 m and the pressure is 145 kPa gauge. Determine the forces F_x and F_y necessary to hold the pipe stationary.

A large, open-topped water tank is being filled from above by a 1.0-cm-diameter hose. The water in the hose has a uniform speed of 11 cm/s. Meanwhile, the tank springs a leak at the bottom. The hole has a diameter of 0.70 cm. Determine the equilibrium level heq of the water in the tank, O measured relative to the bottom, if water continues flowing into the tank at the same rate. heq 1.26 X10-3 Incorrect m

A farmer must pump at least 100 gallons of water per minute from a dam to a field, located 25 f t above the dam and 2000 f t away. She has a 10 hp pump, which is approximately 80% efficient. Find the minimum size of smooth plastic piping she needs to buy, given that the piping is sized by the half-inch. Use ν = 10−5f t/ s. Ignore minor losses.2
