A large, insulated tank (1) is used to storage saturate liquid water at 90°C. The tank is
said to be open at the top to the atmosphere as shown in the figure below.
A centrifugal pump that supplies 7.60 kW of motor energy is used to pump the water
at a rate of 0.757 m3
/min. The water is cooled by passing it through a heat-exchanger
(cooler) where it releases 1 500 kW of heat. The cooler water is delivered to a second
large, insulated tank (2) (similar tank and also open to the atmosphere), which is said
to be 25 m higher relative to the first tank.
Unfortunately, the thermometer of the second tank is malfunctioning and unable to
accurately measure the temperature in this tank. Assuming that there are no frictional
losses, use the principles of chemical engineering to reasonably estimate the final
temperature in the second tank
