Ethylene Glycol Flows At 0 01 Kg S Through A 3 Mmdiameter Thin Walled Tube The Tube 2766293

Ethylene glycol flows at 0.01 kg/s through a 3-mmdiameter, thin-walled tube. The tube is coiled and submerged in a well-stirred water bath maintained at 25°C. If the fluid enters the tube at 85°C, what heat rate and tube length are required for the fluid to leave at 35°C? Neglect heat transfer enhancement associated with the coiling.
