Water is to be withdrawn from a 3-m-high water reservoir by drilling a 1.5-cm- diameter hole in the center of the bottom surface. Disregarding the effect of the kinetic energy correction factor, determine the flow rate of water through the hole for a) a sharp edged entrance followed by threaded 90° bend and then a 3.5m length of wrought iron pipe and finally a fully open Globe Valve b) redo a) for the ideal case with no viscous losses

Problem 3 (4 pts.). A bathyscaphe a small free-diving self-propelled deep-sea submersible), is a sphere of radius 1.5 m located 873.5 m below the sea level. (a) What is the pressure exerted on its surface (here, you can neglect the size of the bathyscaphe compared to the depth of its immersion) and the buoyant force acting on it in the water (b) If a small leak is opened at the top of the bathyscaphe, with...

02. Water at 25 °C is circulated from a large tank, through a filter, and back to the tank as shown in the figure below. The power added to the water by the pump is 271 W Determine the flow rate through the filter. In your solution, follow these steps: Summarize the problem by stating what is given and what needs to be determined State all your assumptions Show the control volume chosen...

8-C) As shown below water is pumped and sprayed through a nozzle into the atmosphere at 20 m/s at an elevation 10 m above the reservoir surface. The mass flow rate is 40 kg/s and the volumetric flow rate is 0.040 m3/s. The large diameter inlet pipe total length is 50 m. The pump effidency is 65%. The longer smaller diameter pipe leaving the pump is 200 m in total length. The pipes have different diameters as indicated below. The...
Problem 3: The following data were obtained for flow of 20°C water at 20 m/hr through a badly corroded 5-cm-diameter pipe which slopes downward at an angle of 8°: pı -420 kPa, zi -12 m, p2- 250 kPa,...
Problem 3: The following data were obtained for flow of 20°C water at 20 m/hr through a badly corroded 5-cm-diameter pipe which slopes downward at an angle of 8°: pı -420 kPa, zi -12 m, p2- 250 kPa, z2- 3 m. Estimate (a) the roughness ratio of the pipe; and (b) the percent change in head loss if the pipe were smooth and the flow rate the same. For water at 20°C, take ρ-998 kg/m3 and μ-0.001 kg/m s
