Chapter 1, Problem 1.46P

A blood warmer is to be used during the transfusion ofblood to a patient. This device is to heat blood takenfrom the blood bank at 10°C to 37°C at a how rate of200 ml/mm. The blood passes through tubing of length2 m, with a rectangular cross section 6 . 4 mm × 1 . 6 mm At what rate must heat be added to the blood to accomplish the required temperature increase? If the fluid originates from a large tank with nearly zero velocityand flows, vertically downward for its 2-m length, estimate the magnitudes of kinetic and potential energychanges. Assume the bloods properties are similar tothose of water.

0.06kg/s of hot air flows through an insulated sheet metal duct of 180 mm Diameter. The air enters the duct at a temperature of 110⁰ and after a distance of 4.5 m gets cooled to a temperature of 70⁰c if the heat transfer officiant between the outer surface of the duct and cold ambient air at 5⁰C is 6.5 w/m²-C calculate the following: a. The heat loss from the duct over its 4.5m at a length of 4.5m b. The heat flux and the duct surface temperature at a length of 4.5m
Consider a cross flow engine oil heater that uses ethylene glycol flowing at a temperature of 1108C to heat the oilinitially at 108C. The ethylene glycol enters a tube bank consisting of copper tubes (k 5 250 W/m·K) with staggered arrangement in a 0.5 m 3 0.5 m plenum. The outside diameterof the 0.5-m-long copper tubes is 25 mm and has a wall thickness of 2 mm. The longitudinal and transverse pitch of the rodbundles is 0.035 m each. The engine oil to be heated flowsinside the tubes with a mass flow rate of 4.05 kg/s. Take theheat transfer coefficient of the oil to be 2500 W/m2·K. If theminimum desired exit temperature of oil is 708C and the measured exit temperature of ethylene glycol is 908C, determine(a) mass flow rate of ethylene glycol and (b) number of tuberows. In your calculation use the following properties for theethylene glycol.r 5 1062 kg/m3 m 5 2.499 3 1023 kg/m·sk 5 0.262 W/m·K cp 5 2742 J/kg·KPr 5 26.12 Prs@408C 5 96.97
Air at 1 atm and 300 °C is cooled as it flows at a velocity of 5.0 m/s through a tube with a diameter of 2.54 cm. Calculate the heat transfer coefficient if a constant heat flux condition is maintained at the wall and the wall temperature is 20 °C above the temperature along the entire length of the tube.
