A purifying air cooler is composed of electronic air filter and a water cooling system. The air passing through the filter is cooled by the water flowing through the cooling pipe located inside the system. Water enters the pipe with a speed of 0.92 m/s at a temperature of 18 C. The water then exits the pipe at 30 C. In the current environment, the purifying air cooler is able to absorb heat from the atmosphere at the rate of 1.654 kW while simultaneously cooling the electronic components inside the device which produces heat at a rate of 0.845 kW. Determine the internal circumference of the pipe to be used for the purifying air cooler. *be careful when selecting the system boundary Answer in meters
