In a power plant, pipes transporting superheated vapor are very common. superheated vapor is flowing at a rate of 0.3kg/s inside a pipe with 5cm in diameter and 10m in length. the pipe is located in a power plant at a temperature of 22°c, and has a uniform pipe surface temperature of 100°c. if the temperature drop between the inlet and exit of the pipe is 30°c and the specific heat of the vapor is 2190 j/kg*k.
1. determine the heat transfer coefficient as a result of convection between the pipe surface and the surroundings.

(science)study the following ocean currents map. an ocean currents map is shown. on the map the locations for san diego, california and savannah, georgia are marked. there is a looping current from the north past san diego and a looping current from the south near savannah which statement is most likely correct about the average temperatures in san diego, california as compared to savannah, georgia? it is higher in savannah because of the cool ocean currents from the south. it is higher in savannah because of the warm ocean currents from the north. it is lower in san diego because of the warm ocean currents from the south. it is lower in san diego because of the cool ocean currents from the north.
