Envision a solar water heater, a device which receives energy from the sun (solar radiation or thermal energy) and is used to heat water. The system is installed on the roof of a building where is receives energy from the sun at a rate of 500 Watts for every 1 m² of surface area. About 35% of the incoming thermal energy is lost to the surrounding environment. The remaining energy is absorbed by the liquid water and the temperature changes from 30 °C to 60 °C. Assuming the system is operating at steady state, find the amount of water (m) that this device can supply at 60 °C if the total surface area of the device is 3 m². Ignore any changes in kinetic energy, potential energy, or change in pressure that might occur in the system.

Envision a solar water heater, a device which receives energy from the sun (solar radiation or thermal
energy) and is used to heat water. The system is installed on the roof of a building where is receives energy
from the sun at a rate of 500 Watts for every 1 m² of surface area. About 35% of the incoming thermal
energy is lost to the surrounding environment. The remaining energy is absorbed by the liquid water and
the temperature changes from 30 °C to 60 °C. Assuming the system is operating at steady state, find the
amount of water (m) that this device can supply at 60 °C if the total surface area of the device is 3 m².
Ignore any changes in kinetic energy, potential energy, or change in pressure that might occur in the
system.
