Question

A flow calorimeter is used to measure the specific heat of a liquid. Heat is added at a known rate to a stream of the liquid as it passes through the calorimeter at a known rate. Then a measurement of the resulting temperature difference between the inflow and the outflow points of the liquid stream enables one to compute the specific heat of the liquid. A liquid of density 0.85 g/cm^3 flows through a calorimeter at a rate of 7.80 cm^3/s. Heat is added by means of a 266 watt heater coil, and a temperature difference of 11.0 degrees C is established in steady-state conditions between the inflow and outflow points. Find the specific heat of the liquid (in joules/kilogram-degree C).
