1. The stagnation pressure ratio across a normal shock in an airflow is 0.6. Estimate the Mach number of the flow entering the shock.
2. Just upstream of a normal shock in an airflow, Ma = 3.0, T = 600 °R, and p = 30 psia. Estimate values of Ma, T0, T, p0, p, and V downstream of the shock.
A 2-m^3 rigid insulated tank initially containing saturated water vapor at 1 MPa is connected through a valve to a supply line that carries steam at 400C. Now the valve is opened, and steam is allowed to flow slowly into the tank until the pressure i..
Figure provides steady-state test data for a steam turbine operating with negligible heat transfer with its surroundings and negligible changes in kinetic and potential energy. A faint photocopy of the data sheet indicates that the power developed..
A water tank consists of a cylindrical part of radius r and height h and a hemispherical top. The tank is to be constructed to hold 600 m3 when led. The surface area of the cylindrical part is 2 rh, and its volume is r2 h. The surface area of the hem..
We want a Cu-30% Zn brass plate originally 1.2-in. thick to have a yield strength greater than 50,000 psi and a % elongation of at least 10%. What range of final thicknesses must be obtained?
Calculate the estimated energy available in the wind using the average wind speed and the Rayleigh function. For bin 16, assume an average wind speed of 16 m/s. Calculate the estimated energy using the method of FAT (13-10) in the chapter. Calculat..
