Cooling water circulates through a water jacket enclosing a housing filled with electronic components. At steady state, water enters the water jacket at 20oC and exits with a negligible change in pressure at a temperature that cannot exceed 24oC. The electronic components receive 2.5 kW of electric power. There is no significant energy transfer by heat from the outer surface of the water jacket to the surroundings and kinetic and potential energy effects can be ignored. Determine the minimum mass flow rate of the water, in kg/s, for which the limit on the temperature of the exiting water is met.
