A sphere 2 m in diameter contains O 2 at 20.68 bar and 27 0 C. How many drums 16 cm in diameter and 60 cm long can be filled to a pressure of 3.44 bar and 18 0 C. Assume that the temperature of the O 2 left in the sphere remains at 27 0 C. (1 bar = 100 kPa) Hint: Volume of sphere = π r 3 , where r = radius of sphere

A sphere with radius 1 m has temperature 11°C. It lies inside a concentric sphere with radius 2 m and temperature 28°C. The temperature T(r) (in °C) at a distance r (in meters) from the common center of the spheres satisfies the differential equation d2T dr2 + 2 r dT dr = 0. If we let S = dT/dr, then S satisfies a first-order differential equation. Solve it to find an expression for the temperature T(r) between the spheres. (Use...

A 3-m-diameter tank is initially filled with water 2 m above the center of a sharp-edged 10-cmdiameter orifice. The tank water surface is open to the atmosphere, and the orifice drains to the atmosphere through a 100-m-long pipe. The friction coefficient of the pipe can be taken to be 0.015 and the effect of the kinetic energy correction factor can be neglected. Someone suggests that it makes no difference whether the pump is located at the beginning or at the...
