Determine the npsh available when a pump draws water at 30 °c from an outside storage tank (open to atmosphere) whose level is 1.5 m above the pump inlet. the energy losses in the suction line total 0.4 m and the atmospheric pressure is 100 kpa(abs). (b) if npsh, for this pump is 11.1 m, is it safe to operate this pump?

Read these sentences from the text. near the equator, the tropics receive the most rain on a consistent basis. as a result, the fresh water falling into the ocean decrease the salinity of the surface water in that region. [. .] . . as the salt content of sea water increases, so does its density. what can you infer about how rain affects the density of surface water near the equator?

Describe what happens to the molecules as water goes from ice to liquid to vapor. be sure to explain what happens to the temperature during the phase changes.
