MEC 241-Fluid Mechanics Tutorial 3 -1 August 2016 Ghazirah Mustapha“To fly, we have to have resistance.” INTRODUCTION TO FUNDAMENTAL CONCEPTS IN FLUID MECHANICS Bernoulli Equations 1.Gasoline (sg=0.67) is flowing at 0.11 m3/s in the pipe shown in Figure 1. If the pressure before the reduction is 415 kPa, calculate the pressure in the 75 mm diameter pipe. Figure 1 2.Water is flowing from point A to B through the point shown in figure at the rate of 0.37m3/s. If the pressure at A is 66.2 kPa, calculate the pressure at B. Figure 2

Figure 3 4.For the tank shown in Figure 4, calculate the volume flow rate of water from the nozzle. The tank is sealed with a pressure of 138 kPa above the water. The depth h is 2.5 m. 5.Calculate the pressure of the air in the sealed tank shown in Figure 4 that would cause the velocity of flow to be 6.1 m/s from the nozzle. The depth h is 3.05 m. Figure 4

Determine the flow rate, Q needed from the inflow pipe if the water depth to remain constant at h = 2.0 m. Figure 5 7.A venturi meter as shown in Figure 6 is used to indicate the pressure difference between two points in a water pipe system. Calculate the manometer deflection, h if the velocity of flow in the 25 mm diameter section is 10 m/s. Figure 6 8.To what height will the jet of water rise for the conditions shown in Figure 7.
