A farmer is to pump water at 70'F from a river to a water storage tank nearby using a 125-ft-long, 5-in-diameter plastic pipe with three flanged 90 smooth bends. The water velocity near the river surface is 6 ft/s, and the pipe inlet is placed in the river normal to the flow direction of water to take advantage of the dynamic pressure. The elevation difference between the river and the free surface of the tank is 12 ft. For a...
An anchor with a density of 700 lb/ft tied to a rope is submerged in water (but is not touching the bottom). It has a volume of 3.o ft3. What is the buoyancy force on that object? 1.

The density of water is given as 1 g/cm3. Determine the specific volume in ft3/lbm. I got 0.077 ft^3/lbm, and it's wrong, I can tell. I'm using the specific volume equation, sv = 1/rho, by the way. Can someone provide insight into this?
A swimming pool of depth 2.5 m is filled with ordinary (pure) water (ρ = 1000 kg/m3). (a) What is the pressure at the bottom of the pool? 1.2550×105 Pa (b) When the pool is filled with salt water, the pressure at the bottom changes by 5.2 x103Pa. What is the magnitude of the difference between the density of the salt water and the density of pure water? Please show your work :)
Let's say there is a retainer wall that typically holds back water. However, there has been an oil spill and we need to calculate the force this new fluid has the wall to determine its capacity. As shown in the diagram, there is 3ft of oil sitting on top of 17ft of water. Oil has a density of 55lbf/ft? and water has a density of 62.4 Ibf/ft?. You can assume the top of the fluid surface is open to the...
A swimming pool of depth 2.7 m is filled with ordinary (pure) water (ρ = 1000 kg/m3). (a) What is the pressure at the bottom of the pool? Pa (b) When the pool is filled with salt water, the pressure changes by 4.5 103 Pa. What is the difference between the density of the salt water and the density of pure water? kg/m3
A water pump delivers 6 hp of shaft power when operating. The pressure differential between the outlet and the inlet of the pump is measured to be 1.2 psi when the flow rate is 10 ft3/s, and the velocity changes to 5 ft/s from 2 ft/s as the water passes through the pump. Determine the mechanical efficiency of this pump assuming the water density to be 62.4 lbm/ft3 (written in decimal form with 3 significant figures).

2 Underground water is to be pumped by a 80 percent efficient 10-kW submerged pump to a pool whose free surface is X m above the underground water level (see Figure 2). The diameter of the pipe is 10 cm on the intake side and 8 cm on the discharge side. Determine (a) the maximum flow rate of water and (b) the pressure difference across the pump. Assume the elevation difference between the pump inlet and the outlet and the...
