Suppose a 70 kg patient is receiving a constant infusion of 1000 mL/hr of a drug at a temperature of 40C. The drug is administered using an intravenous (IV) catheter with an infusion pump that generates 10 watts of heat. The IV fluid and the patient's body are both at a temperature of 37C initially. Assume the specific heat capacity of the drug is 4.18 J/gC and the heat capacity of the patient's body is 3.5 kJ/kgC. What will be the final temperature of the patient's body after 4 hours of drug infusion? Assume no heat is lost to the surroundings.
