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 pump steadily delivers 15.2 kgs of water at the conditions given below. calculate the pump power kw. there is no heat
a low quality-low pressure flow of saturated liquid-vapor mixture of water enters an insulated flash tank located in a
A house is maintained at 1 atm and 24 C and warm air inside a house is forced to leave the house at a rate of 150 m^3/h as a result of outdoor air at 5C infiltrating into the house through the cracks. Determine the rate of net energy loss of th..
One of the main problems encountered in the design of a diesel engine combustion system is the mixing of the air and fuel sufficiently rapidly to ensure complete combustion.
Derive an expression for the velocity vector of the collar D, NVD. The upper arm (B) rotates about a horizontal axis ( nˆx) at a rate q·1
Find the natural frequencies of a cantilever beam of length l, cross-sectional area A, moment of inertia I
A voltage signal is produced by a transducer. The signal contains its strongest frequency component at 50 Hz (amplitude = 5.0 V), plus a weaker component at the second harmonic (100 Hz) with amplitude 2.0 V. In addition, there is noise at 60 Hz with..
metals are usually crystalline and seldom amorphous. most ceramics are crystalline but there are significant examples
Consider a 210 MW steam power plant that operates on a simple ideal Rankine cycle. Steam enters the turbine at 10 MPa and 500o C and is cooled in the condenser to a pressure of 10 kPa. Show the cycle on a T-s diagram with respect to the saturation li..
Within the boundary layer the x-component of velocity increases from u = 0 at the plate surface (y = 0) to u = U0 at a distance 8 above the surface. If the boundary layer thickness increases with x, show that the vertical velocity v(x, y) is every..
An accelerometer is being designed to measure up to 6664 Hz while remaining under 1.7% error. If the natural frequency of the accelerometer is 9613 Hz, determine the damping ratio that will provide 1.7% error.
a rankine cycle with regeneration has steam enter a turbine at 30 bars and 500 degrees c. the condenser pressure is 0.1
