Under laminar conditions, the volume flow q through a small triangular-section pore of side length b and length l is a function of viscosity μ, pressure drop per unit length dp/l, and b. using the pi theorem, rewrite this relation in dimensionless form. how does the volume fl ow change if the pore size b is doubled?

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.
