- The picture below depicts a system for delivering chocolate ganache in liquid form. Thenozzle on the end of the hose requires 140 kPa of pressure to operate effectively. Thehose is smooth plastic with an ID of 25 mm. The chocolate has a specific gravity of 1.1and a dynamic viscosity of 2.0 X 10-3 Pa*s. If the length of the hose is 85 m and there is a change in height of 10 m, determine(a) the power delivered by the pump to the ganache and(b) the pressure at the outlet of the pump.Neglect the energy losses on the suction side of the pump. The flow rate is 85 L/min.arrow_forwardA liquid with negligible viscosity flows through the pipe as shown. This is an overhead view.a. Rank in order, from largest to smallest, the flow speeds v1 to v4 at points 1 to 4. Explain.b. Rank in order, from largest to smallest, the pressures p1 to p4 at points 1 to 4.

- Calculate maximum pressure developed in the slider shoe bearing if the fluid with viscosity of 30Pa-s is flowing through the bearing. The top surface of the bearing is moving with velocity of 3m/s and the dimension in the direction of velocity is 25mm with attitude of 2.2. The film thickness at the entrance is 40micronarrow_forwardWater at 10°C has a kinematic viscosity of 1.30 X 10-6 m2/s flows at the rate of 895.55 L/min from the reservoir and through the pipe shown in the Fig. below. Compute the pressure at point B, considering the energy loss due to friction, but neglecting other losses. Also, use pipe roughness of 1.50 X 10-6 m. Hint: Use the appropriate formula to determine the friction factor, f to 4 decimal places (flow type dependant); g = 9.81 and round off to 3 decimal places for all other step calculations leading to the final answer including the final answer.arrow_forwardAn oil with a specific gravity of 0.84 and a viscosity of 50 cp is flowing downwards in a vertical pipe of inside diameter 3 in. If the water-oil manometer connected to a pitot tube, shows a reading of 25 in, calculate the maximum velocity of the flow of oil in the pipe. Reynolds number of the flow of oil in the pipe. average velocity of the flow of oil in the pipe. piezometric head due to the pitot tube. volumetric flow rate of oil.arrow_forward
