A water pipe is buried 0.37 m (cf. Problem 4.12) below ground in wet soil (a = 7.75 x 10-7 m²/s and k = 2.59 W/m K). The soil is initially at a uniform temperature of 5°C. For sudden application of a convective surface condition of wind with h = 57 W/m² K and T₂ = -21 °C, will the pipe be exposed to freezing temperature (0 °C) in a 10 hour period?
