A horizontal 150mm pipe, in which 40 l/s of oil (S=.8) is flowing, contracts to a 75 mm diameter (left to right). If the pressure in the 150mm pipe is 300kPa, calculate the magnitude and direction of the horizontal force exerted on the contraction (not on the water). Assume that there is no loss of energy in the contraction. Use the gamma of water is equal to 1000 kg/m^3
