Neglect all effects of the capillary tube repeat for a


A fluid-expansion thermometer uses liquid Freon (C = 0.22 Btu/lbm · ?F, ρ = 85.2 lbm/ft3) enclosed in a 0.25-in-ID copper (C = 0.092, ρ = 560) cylinder with a wall thickness of 0.032 in. The thermometer is exposed to a cross flow of air at 400?F, 15 psia, and 20 ft/s. Estimate the time constant for such a thermometer. Neglect all effects of the capillary tube. Repeat for a crossflow of liquid water at 180?F and 20 ft/s. Recalculate the time constant for both of these situations for a stainless-steel bulb (C = 0.11, ρ = 490).
