Water at 10°C flows through the system shown in the figure below at 0.34 m/s. Energy loss in the 40-cm pipe is negligible. Energy loss in the 30-cm pipe is known to be 1.5V2. A mercury manometer indicates that the absolute pressure at the top of the 30-cm pipe is 749.5 mm Hg abs. The pressure of the surroundings is 101,330 Pa. Calculate the power input to the pump. p = 749.5 mm Hg Elevation = 10 m- D= 30 cm -Elevation = 6 m 40-cm diameter Water T = 10 °C Elevation = 2 m W = kW

A pipe set up is given as seen in the figure. The fluid is oil with a specific gravity of 850 kg/m³. The pressure at the exit is atmospheric pressure. The diameter at the entrance is 6.4 cm and the diameter at the exit is 2.2 cm. The volume rate of flow is given as 0.0315 m³/s and thegage pressure at the entrance is 250 kPa. Ignore weight of the fluid and the pipe. Determine the x-component of the force applied at the bolts at section 1. Assume that the atmospheric pressure is 1013 mb. 40° 2

Water flows through a Venturi meter, as shown in the figure. The pressures of the water at locations a and b in the pipe support columns of water that differ in height by L = 10 in. The atmospheric pressure is 14.7 lbf/in², the specific volume of water is 0.01604 ft3/lb, and the acceleration of gravity is g = 32.0 ft/s². Step 1 Patm = 14.7 lbf/in.² g= 32.0 ft/s² Determine the difference in pressure between points a and b, in lbf/in². Does the pressure increase or decrease from point a to point b? Water v = 0.01604 ft³/lb Save for Later Determine the difference in pressure between points a and b, in lbf/in². Pb-Pa = i lbf/in² 4 Attempts: 0 of 4 used Submit Answer

The 1m diameter tank is initially filled with gasoline. There is a 3.1 cm diameter orifice in the bottom. If the orifice is suddenly opened, estimate the time (minutes) for the fluid level to drop from 2m to 1.5 m. Use SG (gas) = 0.7, Cd = 0.66. answer in 2 decimal places.
