(b) Oil flows through a 45 reducing bend as shown in figure 3 below at a rate of 0.61m3/s and the bend is in a horizontal plane. The inlet and outlet diameter of the bend are 410mm and 230mm respectively. Measurements of pressure at inlet and outlet show that the pressure P1 at inlet is 56 kN/m2 and the pressure P2 at outlet is 30kN/m2. If the density of the oil is 850kg/m3, calculate the magnitude and direction of the resultant force on the bend. (11 marks) Figure 3
