Standard atmospheric air [T0 = 288 K, p0 = 101 kPa(abs)] is drawn steadily through an isentropic converging nozzle into a frictionless diabatic (q = 500 kJ/kg) constant area duct. For maximum flow, determine the values of static temperature, static pressure, stagnation temperature, stagnation pressure, and flow velocity at the inlet [section (1)] and exit [section (2)] of the constant area duct. Sketch a temperature-entropy diagram for this flow.
A 600 gram particle (initially at rest at the origin) is subjected to a force of F=15i+20j (N), calculate the average power produced by this force
a car approaches a stationary police car at 80mihr. the frequency of the siren relative to the police car is 500 hz.
An unstable atomic nucleus of mass 1.62x^10-26 kg initially at rest disintegrates into three particles. One of the particles, of mass 5.02x10^-27 kg, moves in the y direction with a speed of 6.00x10^6 m/s. Another particle, of mass 8.44x10^-27 kg,..
