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.
A sightseeing tourist submarine is constructed. The portals along the side can be assumed to be essentially flat, vertical and 1 meter in diameter. Assume a specific weight of seawater of 10,000 N/m3.
A 3400-lb car is traveling in third gear (ratio 2.5 to 1) on a level road at its top speed of 130 mi/h. The air density is 0.00206 slugs/cuft. The car has frontal area of 19.8 sqft, a drag coefficient of 0.28, a wheel radius of 12.6 inches, a driv..
Measurements of water-balance components have been made for a one-year period on a lake with an area of 4.4 km2 with the following results: P = 350 mm, Qsi = 2.33 x 107 m3, Qgi = 2.2 x 105 m3, Qgo = 0.6 x 105 m3, and Qso = .10 x 107 m3.
