Large quantities of liquefied natural gas (lng) are shipped by ocean tanker. at the unloading port, provision is made for vaporization of the lng so that it may be delivered to pipelines as gas. the lng arrives in the tanker at atmospheric pressure and 113.7 k, and represents a possible heat sink for use as the cold reservoir of a heat engine. assuming unloading of lng as a vapor at the rate of 8,000 m3s-1, as measured at 25 c and 1.0133 bar, and assuming the availability of an adequate heat source at 35 c, what is the maximum possible power obtainable and what is the rate of heat transfer from the heat source? assume that lng at 25 c and 1.0133 bar is an ideal gas with a molar mass of 17. also assume that the lng vaporizes only, absorbing its latent heat of 512 kj kg-1at113.7 k.
