One way to do this is to use a common metal of known heat capacity. in the laboratory a student heats 98.19 grams of lead to 98.18 °c and then drops it into a cup containing 83.97 grams of water at 21.38 °c. she measures the final temperature to be 24.63 °c. using the accepted value for the specific heat of lead (see the references tool), calculate the calorimeter constant.

Liquid flows at steady state at a rate of 2 lb/'s through a pump, which operates to raise the elevation of the liquid 100 ft from control volume inlet to exit. the liquid specific enthalpy at the inlet is 40.09 btu/lb and at the exit is 40.94 btub. the pump requires 3 btu/s of power to operate. if kinetic energy effects are negligible and gravitational acceleration is 32.174 tt/s, the heat transfer rate associated with this steady state process is most closely 1)-2,02 btu/s from the liquid to the surroundings 2)-3.98 btu/s from the surroundings to the liquid. 3)-4.96 btu/s from the surroundings to the liquid. 4)-1.04 btu/s from the liquid to the surroundings.
