Question
The wall of a spherical steel tank k, = 17 m. K thick contains hot oil at 100°C. On the outside of the tank 10mm of spray W urethane insulation k, = 0.026 m. K of 1m in diameter and 100 mm h = 16. is added to stop the oil from cooling. If the outside temperature is 25°C, W m².K needs to be added to keep the tank at 100°C for pumping reasons? What are the overall heat transfer coefficients (Uo and Ui)? and h = 5 (₁ m². K how much heat
