steam with 88.6% quality and a flow rate of 750 kg/s enters a condenser operating @ 75 KPa. Saturated liquid leaves the condenser. How much heat is rejected to the cooling system.
Steam @ 10 MPa, 600 degrees celcius enters the first-stage turbine of an ideal Rankine cycle with reheat. The steam leaving the reheat section of the steam generator is @ 500 degrees celcius
If the pipe is to be insulated with glass wool insulation (k=.05 W/m C) in order to decrease the temperature rise of water to .25 degrees C, determine the required thickness of the insulation.
Obtain a new solution, and determine whether any buckling constraints are active. If no buckling constraints are active for L = 10 in., re-run the analysis by increasing L , and estimate the value of L at which at least one buckling constraint b..
Determine the resulting stress equations for σx, σy and τxy given the Airy's stress function ? = a1x^4 + a2(x^3)y + a3(x^2)(y^2) + a4x(y^3) + a5(y^4), where ai are constants. Also determine, if any, the restrictions between constants.
(a) Determine the blade angles at leading and trailing edges of both the rotor and stator at the mean radii, (b) Calculate the mass flow rate and the power required for each stage.
a triangular field with vertices opq has sides op=402m,pq=388m,and qo=254m. find the perpendicular distance from the vertex p to the opposite side.
A volume of 1.8 L of neon gas (monatomic) is at a pressure of 3.4 atmospheres and a temperature of 370 K. The atomic mass of neon is 20.2 g / mol. Calculate the mass of neon gas in SI units.
Bypass air exits at 600 m/s while combustion air exits at 1000 m/s. What is the thrust in kN of this engine?
The velocity at the inlet is controlled so that it changes according to the following expression. V=a-ct^2, where a = 20m/s, c- 0.8m/s. If the tank initially contains 3kg of liquid water, determine the final mass at the end if 4 seconds of flow.
Hollow shaft transmitting power with shear limits. Design a hollow steel shaft to transmit 300 hp at 75 rpm without exceeding a shear tress of 8000 psi. Use 1.2:1 as the ratio of the outside diameter to the inside diameter.
determine the stresses and the rotation of the body at x= 0.050m and y=0.020m is the displacement field compatible?
In a refrigerator 1 kW is removed from the -10 degree C cold space and 1.3 kW is moved into the 30 degree C warm space. Find the exergy fluxes including direction associated with the two heat transfers.
