TexasSure is designed to reduce the number of uninsured drivers and cut costs for responsible Texans, who now pay almost $900 million a year to protect themselves against those with no coverage. Currently, an estimated 20 percent of Texas drivers are uninsured.
TexasSure is the financial responsibility verification program created by the 79th Texas Legislature, Regular Session, in Senate Bill 1670.
Answer:
0.39J/s
Explanation:
Length of 1 tube = 3.7m
Length of 400 tubes in the heat exchanger = 3.7×400 = 1480m, Temperature difference = 23°C = 296K
Outer surface
Rate of heat transfer = (heat transfer coefficient×area×log mean temperature difference)/length
diameter (d) = 25mm = 0.025m, area = πd^2/4 = (3.142×0.025^2)/4 = 0.000491m^2
Rate of heat transfer = (6820×0.000491×296)/1480 = 0.67J/s
Inner surface
diameter = 23mm = 0.023m, area = (3.142×0.023^2)/4 = 0.000416m^2
Rate of heat transfer = (3410×0.000416×296)/1480 = 0.28J/s
Heat transfer rate between the two surfaces = 0.67 - 0.28 = 0.39J/s
