A boad initially stationary at water,fires a shell in i direction,The shell's air speed =822 m/s.The shell was in the gu8n for .16s, and the force exerted on the shell decrease linearly fromthe initial force to zero over the firing interval. The shell mass in 10Kg, and the boat's mass = 1198Kg. Find the maximum force that acted on the shell.
if a pipeline is horizontal, what is the porportion of the potential energy head at the upstream crossection that is changed to kinetic energy head at the downstream crossesction
Describe how test flumes and associated equipment are used to assess and confirm hydraulic behaviour in open channel
Calculate the Air flow required in CFM to transfer 5,396 BTU/Hour in an HVAC duct given that the temperature difference (Delta-T) between the room and the supply air is 21 DegF.
A piston-cylinder device contains 0.2kg of water initially at 800 kPa and 0.06m^3. Now 200 kJ of heat is transferred to the water while its pressure is held constant. Determine the final temperature of the water.
A balloon is being inflated at the rate of 15m^3/min. At what rate is the diameter increasing after 5 min? Assume that the diameter is zero at time zero.
The pipes holding the boards were placed 10 ft apart across the dam. There were 20 pipes and each one was designed to fail under a bending moment of 1625 ft-lb how deep will the water be on the flash boards when failure occurs
To prevent this high compression load from buckling the copper pipe, a solid steel support of 2 1/2 inch diameter is placed inside the copper pipe. The copper pipe is 8.000 inches long. The steel support is 8.0001 inches (exactly 1 mil = 1/1000 in..
A 32-in.-wide by 0.125-in.-thick by 110-in.-long steel sheet is to be formed into a hollow section by being bent through 360° and having the long edges welded (i.e., butt-welded) together. Assume a cross-sectional medial length of 32 in.
A Pelton wheel, located at an elevation of 200.0 m, is used to extract power from a reservoir at an elevation of 800 m. A penstock 1500 m long and 0.8 m in diameter connects the reservoir with the nozzle of the Pelton wheel.
The following data were obtained for a plate-and-frame filter of total area A=500 sq cm. operating under a constant pressuredrop of 0.1 atm: Time t (min): 50 75 100 Volume of filtrate V (liter): 9.7 12.3 14.0 The filtrate is essentially water.
What annual investment is required at 8% per year compounded annually to accumulate to $100,000 at the end of 20 years?
The inflow to a small reservoir during a storm may be described by the equations Q=1000(1-e^-kt) where Q= flow in cfs k= runoff rate = 1.0 per hour t = time in hours The outflow through the dam gates is held constant at 800 cfs.
