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

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

explanation:

i wanna say it’s between b and d, leaning more towards b.
