1.A smooth plastic garden hose 30 feet long is used to drain water from a pond into an open field. The hose has an inside diameter of 2 inches. If viscous effects are neglected (inviscid/frictionless flow) and the hose outlet is 10 feet below the surface of the pond, calculate the volumetric flow rate inside the hose in units of gallons per minute (gpm).
2.Draw and explain a pump curve that illustrates the effect of throttling in the CLOSED direction (i.e., reducing flow) the discharge valve for a constant speed centrifugal pump installed in a cooling water system.
given the following cost expenditures for small warehouse answer project calculate the peak financial requirement, average overdraft.
A steel bar is attached to a wood support beam with four 20 mm diameter lag screws. The steel bar is 75-mm-wide by 6-mm-thick. For the steel bar, the yield strength is 260 MPa and the ultimate bearing strength is 350 MPa.
A two-dimensional flow field is given by u=2+xy+3t^2, v=2xy^2+t. Find the velocity and acceleration of a particle of fluid at point (2,3) at t=4. Specify units in terms of L and T.
Find the minimum length of runway required for the landing (I found to be 300ft). Find the position on the runway where the speed is 50ft/s and the time it takes for the speed to reach 50ft/s
How was this answered reached? what equation was used? equation of a line? could you please explain how the answer was reached and a detailed explanation of the math behind it.
one atmospheric air stream at 15 c and 30 percent relative humidity is mixednadiabatically with another air stream at 30c and 70 percent relative humidity in a steady flow process
What percent increase in shear force would be experience on the flat sides of a 40 ft long truck trailer as the truck speed increases from 65 mph to 75 mph? Kinematic viscosity of the air is 1.6x10^4 ft^2/s.
A steel bar serving as a vertical hanger to support heavy machinery in a factory is attached to a support by the bolted connection. The main part of the hanger has a rectangular cross section with width b1 = 1.5 in. and thickness t = 0.5 in.
A jet of water of diameter 75mm moving with a velocity of 25m/s strikes a fixed plates in such a way that the angle between the jet and plate is 60 find the force exerted by the jet on the plate.
