Blood passing through a 2.5 mm ID steel tube is to be warmed from 320 C to 37.30C. The volumetric flow rate is 15 mL/s and the tube wall is heated electrically to provide a uniform flux. It is important to prevent the wall temperature from exceeding 430 C to prevent damage to blood. Approximating blood properties to that of water, what is the minimum tube length that is required? =996.2 kg/m3, Cp=4176 J/kgK, / =7.51x10-7m2/s, k=0.619 W/mK. Nu=2 Gz
