Q4/ The outlet pipe from a pump is a bend of 45° rising in the vertical plane as shown in Fig. 4. The bend is 150 mm diameter at its inlet and 300 mm diameter at its outlet. The pipe axis at the inlet is horizontal and at the outlet it is 1 m higher. By neglecting friction, calculate the force and its direction if the inlet pressure is 100 kN/m² and the flow of the water through the pipe is 0.3 m³/s. The volume of the pipe is 0.075 m³?
