1. Water from a garden hose is sprayed against your car to rinse dirt from it. Estimate the force that the water exerts on the car. List all assumptions and show calculations.
2. A Pelton wheel vane directs a horizontal, circular cross-sectional jet of water symmetrically as indicated in Fig. P5.74 and Video V5.6. The jet leaves the nozzle with a velocity of 100 ft/s. Determine the x-direction component of anchoring force required to
(a) hold the vane stationary,
(b) confine the speed of the vane to a value of 10 ft/s to the right. The fluid speed magnitude remains constant along the vane surface.
a 2 m3 tank containing nitrogen at 25oc and 500kpa is connected through a valve to another tank containing 3kg of
Determine the critical load Pcr for the structure from figure part (a).
The tower is held in place by three cables. If the force of each cable acting on the tower is shown, determine the magnitude and coordinate direction angles of the resultant force. Take x = 20 m, y = 15 m
air enters an adiabatic compressor at 197 kpa and 316 k and exits at a temperature of 508 k. determine the power kw for
a steam rankine cycle operates between pressure limits of 2500 psia in the boiler and 1psia in the condenser. the
6 kg of an ideal gas is in a volume of 1 m3 at 250degc. the gas undergoes a constant pressure change of state until the
neglecting the effects of radiation absorption emission and scattering within their atmospheres calculate the average
Calculate the following based on the full nominal (rough) dimensions:- the maximum bending stress, the maximum bending stress if the boards are glued together and the maximum shear stress in the middle glued joint.
A steam power plant operates on an ideal reheat-regenerative Rankine cycle with one reheater and two open feed water heaters. Steam enters the high-pressure turbine at 1,500 psia and 1,100 degrees Farenheit and leaves the low-pressure turbine at 1 ps..
a boat of length 50 m is designed to cruise at 30 mph and is to be tested in a tow tank with a model of length 0.5 m.
A cylindrical specimen of a metal alloy 48.0 mm long and 9.72 mm in diameter is stressed in tension. A true stress of 368 MPa causes the specimen to plastically elongate to a length of 53.5 mm.
A fluid flow axially in the annular region between two concentric pipes with radii R1 and R2>R1, respectively. Assume the flow is steady, incompressible, axisymmetric, fully-developed, and has no swirl. Also neglect all body forces.
