Asmooth steel (sg = 7.86) sphere is dropped in gasoline at 20°c. ignoring its acceleration phase, what will be its terminal (constant) fall velocity? take d = 0.5 cm. for gasoline at 20°c, take rho ≈ 680 kg/m3 and μ ≈ 2.92e−4 kg/m⋅s. for steel, take rho ≈ 7800 kg/m3. take π = 22/7. round the answer to one decimal digit. take cd ≈ 0.4.

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.
