Figure 1 shows a hot gas stream at 500 °C being cooled to 300 °C by transferring heat to the liquid water that enters at 20 °C and exits at temperature Tout °C). Assume that the heat exchanger is insulated. The cooling water does not mix with the gas. Calculate the amount of heat (in kilojoules) that has been absorbed by the cold water.

Question
Figure 1 shows a hot gas stream at 500 °C being cooled to 300 °C by transferring heat to the
liquid water that enters at 20 °C and exits at temperature Tout °C). Assume that the heat
exchanger is insulated. The cooling water does not mix with the gas. Calculate the amount of
heat (in kilojoules) that has been absorbed by the cold water.
Transcribed Image Text:Figure 1 shows a hot gas stream at 500 °C being cooled to 300 °C by transferring heat to the
liquid water that enters at 20 °C and exits at temperature Tout (C). Assume that the heat
exchanger is insulated. The cooling water does not mix with the gas. Calculate the amount of
heat (in kilojoules) that has been absorbed by the cold water.
