In a flow over a flat plate, the stanton number is 0.005: what is the approximate friction factor for this flow a)- 0.01 b)- 0.02 c)- 0.001 d)- 0.1

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.
