he 20@kg wheel has a radius of gyration about its centerOofkO = 300 mm. When the wheel is subjected to the couple moment, it slips as it rolls. Determine the angular acceleration of the wheel and the acceleration of the wheel's center O. The coefficient of kinetic friction between the wheel and the plane ismk = 0.5.
air enters a gas turbine with two stages of compression and two stages of expansion at 100 kpa and 17 degree celsius.
a battery of cylindrical hollow-fiber membranes is operated at steady state to concentrate a bacterial suspension from
A throttling valve is used in an air conditioning system to reduce the pressure of refrigerant: R134a as it flows from a condenser to an evaporator. The refrigerant enters the throttling valve at a pressure of 140psia and a temperature of 95F and lea..
Consider an air-standard Otto cycle starting at 9 psia, 77 deg F, with a compression ratio of 11, and a specific heat addition of 200 Btu/lbm. Assume 80% adiabatic compression efficiency and a 75% adiabatic expansion efficiency. Calculate the overall..
a regenerative steam power cycle has a closed feedwater heater that heats 20 kgs of water from 100degc 20 mpa to
calculate the specific volume for ammonia gas at 450 k and 4000 kpa using a ideal gas equation b compressibility chart
Specify the spring constant,the damping coefficient, and the unbalance of the exciter.
Based solely on the flow correlation above and your knowledge of the structure of the laminar flow temperature boundary layer, derive the rate of growth of the boundary layer δ(x)
Consider heat transfer through a wall comprised of two solid layers, each 4m x 4m. When perfect contact is maintained between the layers, the steady state temperature profile across the wall might look like that shown below
two streams of air mix in a constant-area mixing tube the primary stream enters the mixing tube at station 1 with a
a power plant based on the rankine cycle is under development to provide a net power output of 10 mw. solar collectors
Saturated liquid steam at 2 MPa steadily enters a valve where it is throttled to 0.3 MPa. The inlet and outlet diameter is 1 cm. The flow rate is 0.012 kg/s. Determine the outlet density [kg/m3] of the steam. Also show that it is reasonable to neglec..
