The plant draws 10000 pounds per hour of natural gas that has been throttled down to 15 psig. Find the temperature drop due to throttling and the preheating electric heater power required so that the temperature of the gas will be back to its original value after throttling.
How to tell if you're having a hot flash: The rise in temperature involved in hot flashes is not severe. During a hot flash, the blood rushing to the vessels nearest the skin may raise skin temperature by five to seven degrees, but core body temperature will not usually rise above a normal 98.6 degrees.he middle layer of the skin, or dermis, stores most of the body's water. When heat activates sweat glands, these glands bring that water, along with the body's salt, to the surface of the skin as sweat. Once on the surface, the water evaporates.
Blood and temperature control-Higher. When we are too hot, blood vessels supplying blood to the skin can swell or dilate (vasodilation). This allows more warm blood to flow near the surface of the skin, where the heat can be lost to the air. This is why some people's skin looks redder when they feel too hot. When we are too cold the blood vessels supplying warm blood to the skin become narrow or constrict (vasoconstriction). This reduces the flow of warm blood near the surface of the skin, and reduces heat loss. This is why some people's skin looks paler when they feel too cold.
