## Homework Statement

Fast-flow blood warmers (pictured below) can be used to heat blood products (carefully and uniformly) when rapid, high-volume transfusions are necessary, in order to prevent hypothermia in the patient. The blood product density and specific heat can be assumed to be 1.12 g/cm3 and 3.8 kJ/kgK, respectively. If the blood product initially is at 8 degrees Celcius, the target temperature is 37 degrees Celcius, and the maximum transfusion rate is 900 ml/h,

*what is the theoretical heating power (W) needed for this machine?*

## Homework Equations

q=mcΔT

W=J/s

Density=m/V

## The Attempt at a Solution

Sorry, this is a new type of problem that our prof. gave, and he also gave no hint/formula so I am lost. Where do you implement the transfusion rate in the calculation? Do I treat it as the volume?
