Question
Steam is being transported in a pipe outer diameter of the pipe is 8
cm, and the surrounding air temperature is 20 °C. On the surface of
the pipe, the combined heat transfer coefficient is 35 W/m2*K. The
surface temperature of the pipe is 150 °C.Steady-state conditions
exist. The power used to generate the steam is obtained from natural
gas. The declared CV (gross) is a approximately value of 38. MJ/m3.
and estimate and calculate the financial loss due to heat loss from
this steam pipe within a period of one year.(The determined valid
natural gas price (wholesale price excluding taxes) has been
announced as 1.251652 TL / Sm3.)
