Apressure gage connected to a tank reads 60 psi at a location where the barometric reading is 29.1 in hg. determine the absolute pressure in the tank. take rhohg = 848.4 lbm/ft3.

513 psi step by step in explanation

Explanation:

First We need to convert the inches to ft using a conversion factor then:

1 in= 0.083ft , so  29.1 in=2.42ft

We use the equation of fluids that is:

P= P, +ρgh

We need to include the conversion of psf to psi

1 psf=0.0069 psi

P= P, +(ρgh*0.0069)

P=60 psi + 848.4 * 32*2.42ft*0.0069

P=513psi

6/12=1/2

step-by-step explanation:

5 w for 1hr = 5x60x60 joules=300x60=3000x6=18,000j as total energy conversion. efficiency of bulb needed for radiant to thermal within 18000
