PRINTER VERSTON BACK NEXT Chapter 14, Problem X4 A blimp is cruising slowly at low altitude, filled as usual with helium gas. Its maximum useful payload, including crew and cargo, is 1.50E+3 kg. The volume of the helium-filled interior space is 7.76E+3 m. The density of helium gas is 0.16 kg/m, and the density of hydrogen is 0.081 kg/m. How much more payload could the blimp carry if you replaced the hellurn with hydrogen? Number Units the tolerance is +/-2%...
If the speed of flow past the lower surface of an airplane wing is 101 m/s, what speed of flow over the upper surface will give a pressure difference of 889 Pa between upper and lower surfaces? Take the density of air to be 1.30 × 10-3 g/cm3. Assume the lower surface is at the higher pressure.
