The output shaft power p, of a hydraulic turbine is a function of water density p, head (hydraulic energy per unit mass of water) gh, flow rate q, rotor diameter d, and rotating speed n. ps=f(p, q,n, d,gh) express the shaft power in non-dimensional form.

Acertain flow of air (at stp) has a velocity distribution given by v i (in ft/s). if this flow is going through a 4 ft square area in the yz-plane (centered at the origin), what is the mass flow rate (in lbm/s)?

Atank with constant volume contains 2.27 kg of a mixture of water phases (liquid-vapor). in the initial state the temperature and the quality are 127 °c and 0.6, respectively. the mixture is heated until the temperature of 160 oc is reached. illustrate the process in a t-v diagram. then, determine (1) the mass of the vapor in kg at the initial state, (2) the final pressure in kpa.

What is creep? what is stress relaxation?
