Avacuum gage attached to a power plant condenser gives a reading of 27.86 in. of mercury. the surrounding atmospheric pressure is 14.66 lbf/in. determine the absolute pressure inside the condenser, in lbf/in. the density of mercury is 848 lb/ft and the acceleration of gravity is g = 32.0 ft/s? .

absolute pressure =  1.07 lbft/in^2

Explanation:

given data:

vaccum gauge reading h = 27.86 inch = 2.32 ft

we know that

gauge pressure p is given as

we know that  

1 ft = 12 inch

therefore

so absolute pressure =

                                   = 14.66 - 13.59 = 1.07 lbft/in^2

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.
