    Solve Hard Fluid Problem: Calculate Minimum Work & Power of Pump

    A pump, submerged at the bottom of a well that is 35 m deep, is used to pump water uphill to a house that is 50 m above the top of the well. The density of water is 1000 kg/cm^3. All pressures are gauge pressures. Neglect the effect of friction, viscosity. A) REsidents of the house use .35...

    Fluid Mechanics Problems: Pressure, Diving Depth, and Density Calculations

    ty I got the last 1 still trying to figure out and may be u can help 10kg raft made of driftwood w/ specific gravity .60 floats on the surface of a calm pond. Density of water = 1000 kg/m^3 Calculate the volume of the raft Im not sure if the problem missing some unit I need Density of the raft...

    Fluid Mechanics Problems: Pressure, Diving Depth, and Density Calculations

    1)A cup contain 15cm lvl water. A 29cm straw is place into the cup, at the end of the straw is 1cm from the bottom. If a person sucks on the straw, what gauge pressure is needed at the top of the straw to allow the water to run out of the top and into his mouth. P=pgh 1000(9.8) .29 = 2842 Pa...

    1/2(2M)[(Squaroot 2gR)/2]^2 M*[ (2gR)/4 ] it is 1/2mgR

    KE before mgR KE after collide 1/2(2M)[(Squaroot 2gR)/2]^2 => 1/2mgR So it lose 1/2 of it KE?

    A quarter-circle of radius R, block A mass M is release from the top of the quarter-circle, slide down the curve section. And collide inelastically with identical block point B. The two blocks move together to the right and stop with the distance L. The coefficient of Kinetic energy between the...
