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 specific heat of whole blood can be assumed to be 3.8 kj/(kg k). if the whole blood initially is at 7oc, the target temperature is 37oc, and the maximum transfusion rate is 1,010 ml/h, what is the theoretical heating power (w) needed for this machine?
