One-dimensional, steady flow has velocity components u = Ax, v = 0, w = 0, where A is a constant. Place yourself in the frame of reference of a particle in this flow. You observe things as a function of time t in this Lagrangian frame of reference. Supposing that u = 1 at t = 0, derive expressions for:

. the acceleration Du/Dt that you expreience

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.
