Using Raoult's Law or Henry's Law, as appropriate, calculate the pressure and mole fractions in the vapor phase for a system containing a liquid that is 0.3% N2 and 99.7% water (by moles) in equilibrium with its vapor at 80 °C.
Compare P with the minimum gripping force Ps required to hold the sphere in static equilibrium in the 30° position.
Calculate the drag force per unit length of the strut if it is moving at V = 10 mph in water. Compare this result to the force per unit length of a 1 in diameter circular strut.
A permeameter with a cross-sectional area of 400 cm2 contains 3 soils in 50 cm thick layers. A total head difference of 2.0 metres results in a flow rate of 100 cm3/s. The head loss through the top layer of soil is 50 cm.
