Which of the following explains why the Federal Aviation Administration and the United States Maritime Administration work closely with the U. S. Customs Agency?

-to create specific regulations for weight loads on air and sea transports

-to design entry and exit points out of the country to control air and sea flow

-to prevent oil spills and other environmental disasters(this one is wrong)

-to ensure that no illegal substances are smuggled on air and sea transports

To design a steam turbine to produce 12,000 hp power. a engineer comsiders using a steady state stean low st 1160fr and engineer considers using a steady state steam flow at 1160°r and 450 psia to drive this steam turbine. the exhaust of the steam is cooled by the lake (vacuum). heat losing to the surroundings is measured at a rate of 555.55 btu/s. (a) sketch the system with the given conditions. (b) neglecting kinetic and potential energy changes from inlet to exit, determine the volumetric flow rate of the steam at the inlet, (ft'/hr). must clearly show unit conversions at crtical terms.
