Fundamentals of Heat and Mass Transfer – Problem 1.46

ByAnthony

A blood warmer is to be used during the transfusion of blood to a patient. This device is to heat blood taken from the Blood Bank at 10°C to 37°C at a flow rate of 200 mL/min. The blood passes through tubing of length 2 m, with a rectangular cross-section of 6.4 mm x 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 similar velocity and flows vertically downward for its 2-m length, estimate the magnitudes of kinetic and potential energy changes, assuming the blood’s properties are similar to those in water.

Design of a Power Plant Cooling System

ByAnthony

Background The purpose of this design project is to design a cooling system for a power plant, which includes designing a heat exchanger and a piping system from the river to the condenser to cool the superheated steam from the Rankine cycle. The Rankine cycle produces 1.4MW of power from the steam turbine.  The average…
