Water flow in steel pipe at a temperature of 50o C as shown in the figure. The pipe is wrapped with thermal isolation. Air is flowing over the pipe at a temperature of -5o C and a speed of 3 m/sec. It is known that 1kWh costs 0.05$ Find the daily cost of the heat losses per meter without the pipe isolation? What is the daily cost saving when using the isolation?

Question
Water flow in steel pipe at a temperature of 50o C as shown in the figure. The pipe is wrapped with thermal isolation. Air is flowing over the pipe at a temperature of -5o C and a speed of 3 m/sec. It is known that 1kWh costs 0.05$
Find the daily cost of the heat losses per meter without the pipe isolation? What is the daily cost saving when using the isolation?
