Determine the specific gravity of spherical particles, D=(1/200 in), which drop through air at 33degrees F at a speed U of 0.3 ft/s. The drag force on a small sphere in laminar motion is given by 3(pi)(mu)DU. This problem is in Fluid Mechanics by Victor Streeter.
If one cubic centimeter of water has a mass of 1 gm, find the pressure at a depth of 5m in a tank of water.
Determine the mass of wire having a relative density of 8.77 which must be wrapped around a cork weighing 15 g in order that the cork shall just sink in fresh water. The cork's relative density=0.24.
This is a past exam question. Please help me understand how to go about questions a and b. I think I need some kind of double integral or something?
Find the cardiac output of a heart using Fick's method given that the concentration of oxygen in the pulmonary artery is 14mL/100 mL (Cin) and in the vein is 20 mL/100 mL (Cout). Oxygen uptake (U) by the lungs is 300 mL/min. Assume that blood flows at a constant rate Q mL/min (the cardiac output).
