Question: PLEASE SOLVE USING GIVEN TWO CIRCLED FORMULAS Blood passing through a 2.5mmID steel tube is to be warmed from 320C to 37.30C. The volumetric flow

PLEASE SOLVE USING GIVEN TWO CIRCLED FORMULAS

Blood passing through a 2.5mmID steel tube is to be warmed from 320C to 37.30C. The volumetric flow rate is 15mL/s and the tube wall is heated electrically to provide a uniform flux. It is important to prevent the wall temperature from exceeding 430C to prevent damage to blood. Approximating blood properties to that of water, what is the minimum tube length that is required? =996.2kg/m3,Cp=4176J/kgK,/=7.51107m2/s,K=0.619W/mK
