The acceleration of a particle is defined as a=25-3x^2, a is expressed in m/sec^2, and x is in meters. The particle starts with no initial velocity at the position x=0. Find a)the velocity when x=2meters. b) the position were the velocity is again zero. c) the position where the velocity is at its max.
the load on a 2 inch diameter hydraulic cylinder increases from 10000lb to 15000lb. due to compressibility of oil the
A large stationary Brayton cycle gas-turbine power plant delivers a power output of 100MW to an electric generator. The minimum temperature in the cycle is 300K
A turbine takes in 2 kg/s neon at 27C and 200 kPa with negligible velocity. The produced work is 75 kW and 30 kW of heat leaks into the turbine from the surroundings. The neon exits at 100 kPa and 230 K. Find the exit velocity of the neon.
Infrastructure Difficulty in siting new plants Cost and efficiency losses (5-8%) in transmission Power quality and dependability issues Higher Efficiency Efficiency is reduced by fuel processing Fuel is relatively inexpensive and plentiful (now) L..
what is the minimum distance d at which the brakes must be applied to avoid a collision? Treat the train as a particle and assume that the railroad tracks are rectilinear and horizontal.
a circular coil having 19 turns and a radius of r 17.6cm carries a current of 3.80a. it is placed in a uniform
a simple pulley with the given radius r used to lift heavy objects is positioned 10 feet above ground level. Given that the pulley rotates theta degrees, determine the height to which the pulley is lifted.
now consider the cooling process. it takes place in a heat exchanger hx. warm air. at 75 f is flows into one side of
Determine the expected diffraction angle for the first-order reflection from the (310) set of planes for BCC chromium when monochromatic radiation of wavelength 0.0711 nm is used.
Lawn mower engines normally have finned surfaces directly attached to the engine block, with no radiator, in order to achieve the required cooling. Why might the cooling strategies be different in these two applications?
The heat transfer coefficient in the oven is 25W/m^2K. Calculate rate of heat transfer per m^2 area.
What would happen if the air filter was partially choked. If the piston rings were leaking state what you would expect the results of a, b, c, and d above would be.
