For transfusion of blood to a patient, it is decided to have a heat exchanger which heat the blood from 6°C to 37'C at a flow rate of 590ml/min. The tube is rectangular in cross-section with 6.5 mm by 1.8 mm sandwiched between two plates head at a constant temperature of 40°C. Compute the length of the tubing required to achieve the desired outlet conditions at the specified flow rate. Assume the flow is fully developed and the blood has the same properties as water. Properties are: Cp=4180 J/kg. K, density=1000 kg/m3, Pr=5.83, k=0.613 W/m.K What is the Reynolds no? What is the velocity of blood in m/s? What is the heat transfer coefficient in SI units?

Question
Transcribed Image Text:For transfusion of blood to a patient, it is decided to have a heat exchanger which heat the blood
from 6°C to 37'C at a flow rate of 590ml/min. The tube is rectangular in cross-section with 6.5 mm
by 1.8 mm sandwiched between two plates head at a constant temperature of 40°C. Compute the
length of the tubing required to achieve the desired outlet conditions at the specified flow rate.
Assume the flow is fully developed and the blood has the same properties as water.
Properties are: Cp=4180 J/kg. K, density=1000 kg/m3, Pr=5.83, k30.613 W/m.K
What is the Reynolds no?
What is the velocity of blood in m/s?
