To be able to quantify the energy produced by a solar collector, the following formula is utilized: $$Q = m C_p (T_r - T_s)$$ where \(Q\) is the collector heat rate; \(m\) is the mass flowrate; \(C_p\) is the specific heat; \(T_r\) is the temperature of the liquid in the return path; and \(T_s\) is the temperature of the liquid in the supply path. Using 3000 operating hours in a year, compute the yearly heat rate production in kilojoules of a solar collector if \(m = 2\rm\ kg/h\), \(C_p = 4\ \rm kJ/(kg\,K)\), \(T_r = 425\rm\ K\), and \(T_s = 375\rm\ K\).
