Answer to Question #290844 in Molecular Physics | Thermodynamics for eysiii

Question

Barometric Pressure is 29.89 in Hg. Convert the following

a. 68 psig to mm Hg absolute

b. 100 kPag to psia

c. 1000 mm Hg absolute to kPag

d. 5 psia to in Hg vacuum

Answer 1

$1psig=51.71mmHg\\1kpag=0.15psia\\1mmHg=0.13kpag\\1psai=2.04~in~Hg$

(a) 68psig to mm Hg absolute

$~~~~=68\times51.71=3516.28mmHg$

(b) 100 kPag to psia

$~~~=100\times0.15=f15psia$

(c) 1000 mm Hg absolute to kPag

$~~~=1000\times0.13=130kpag$

(d)5 psia to in Hg vacuum

$~~=5\times2.04=10.2in~Hg$
