Serway & Jewett — The First Law of Thermodynamics: Problem 33.

A flow calorimeter is an apparatus used to measure the specific heat of a liquid. The technique of flow calorimetry involves measuring the temperature difference between the input and output points of a flowing stream of the liquid while energy is added by heat at a known rate. A liquid of density \(900 \text{ kg/m}^3\) flows through the calorimeter with volume flow rate of \(2.00 \text{ L/min}\). At steady state, a temperature difference \(3.50^\circ\text{C}\) is established between the input and output points when energy is supplied at the rate of \(200 \text{ W}\). What is the specific heat of the liquid?
