The pipes transporting 30 liters/s of 2 C chilled water from an ice storage system to a building are 20 cm. in diameter. The pipes are outdoors and exposed to the wind for 100 m. a. Determine the thickness of mineral fiber insulation necessary to prevent a heat loss of less than 100 W/m of length for design conditions of a 5 m/s wind at 35 C. b. Determine the temperature drop over the 100 m length.
