A spherical balloon contains 2 kg of water at 230 degrees C, 400 kPa (the specific volume is 0.5951 m^3/kg). The balloon material is elastic and the pressure inside is always proportional to the valloon diameter. The water is now allowed to cool until the volume is 30.79% of the initial volume. (1) I shte cooling process polytropic? If so, what is the value of n? (2) Find the final state pressure. (3) Compute the work done for this process considering the water as a closed system.
locate the initial and final states on a sketch of the T-v digram. determine the mass of vapor present at the initial and final state, each in kg.
If it is known that the value of the stress exponent n for this alloy is 8.2, compute the steady-state creep rate at 1300 K and a stress level of 89 MPa.
The total force Fa + Fb exerted on the shelter is in the direction parallel to the line L and it's magnitude is 400 lb. Graphically determine the magnitudes of Fa and Fb.
Knowing that crank AB has a constant angular velocity of 160 rpm counterclockwise, determine the angular velocity of rod BD and the velocity of collar D when a. delta=0, b. delta = 90.
Horsepower and efficiency of three-phase motor, If a fully loaded 440V, three-phase motor draws 12.4 A at 86% power factor (pf). It's speed is 1730 rpm and its torque output to a mechanical load is 29.1 lb-ft x 1.356 = 39.5 Nm.
An ideal vapor-compression refrigeration system operates at steady state with Refrigerant 134a as the working fluid. Superheated vapor enters the compressor at 30 lbf/in2, 20F, and saturated liquid leaves the condenser at 140 lbf/in2. The refriger..
Use the bisection method to determine the drag coefficient (cd) needed so that a 80 kg bunjee jumper has a velocity of 36 m/s after 4 s of free fall.
Two bars, one having a circular section of radius b, the other an elliptic section with semiaxes a,b. For equal angles of twist, which bar experiences the larger shearing stress?
Find the final state inside the tank, A tank contains 2kg of nitrogen at 10K with a quality of 50%.Through a volume flow meter and valve, 0.5kg is now removed while the temperature remains constant.
