A solar water heater is used to increase the temperature of liquid water in an open cattle watering tank from 3.00°C to 18.0°C in a steady state, steady flow process.

The mass flow rate of the water through the tank is 1.50 kg/s, and the solar heater adds 100. kW to the water.

Determine the first and second law efficiencies of this system. The temperature of the local environment (ground state) is 0.00°C.
