An IV warmer heats 125 mL/h of IV fluid from room conditions (20 C and 1 atm) to body temperature (37 C). Assume that the fluid properties are similar to those of water. a) Determine the required electrical power input for this device (W). b) One evening the warmer was inadvertently left outside with 45 mL of fluid in the tubing and the fluid temperature dropped to -15 C. To avoid damaging the pumping system, the decision was made to turn on the heating element to thaw the fluid. How long (min) will it take to thaw the fluid completely so that the warmer can be drained and cleaned?
