A 6 in x 20 ft uninsulated B.I pipe conveys steam at 385 °F with an average ambient temperature of 85°F. if the cost of the fuel is PhP 250.00 per 106 BTU with the net energy conversion efficiency of 75%, what is the annual cost of the heat lost? For 6 in. pipe schedule 80:Do = 6.625 inDi = 5.761 in For iron:k = 30 BTU/ hr ft °F for the surface coefficients:hi = 1000BTU/ hr ft2°F ho = 2 BTU/hr ft2 °FA heat exchanger is heating water on the tube side with steam condensing on the shell side. The water is entering at 45 0 F and exiting at 175 0 F. No instruments are available for measuring the tube side water flow but condensed steam from the shell side is being collected at a rate of 43 GPM. If the tube area of the exchanger is 350 Ft2 , and the overall heat transfer coefficient clean was 900 BTU/Hr.Ft2 F0, how much has the overall heat transfer coefficient changed, if at all?
