Question

Given the barometric pressure of 14.7 psia (29.92 in Hg abs) make these conversions: a.) 90 psig to psia and to atmosphere, b.) 15 in Hg vacuum to in. Hg abs and to psia, c.) 20 psia to psi vacuum, and to Pa, d.) 15 in Hg gage to psia, to torrs, and to Pa. ( 1 atmosphere = 760 torrs) *

Answer 1

a)

90 psig=104.7 psia,

90 psig=7.12 atm,

b)

15 in Hg=13.4 in Hg abs,

15 in Hg=7.37 psia,

c)

20 psia=5.3 psi,

20 psia=147895 Pa,

d)

15 in Hg=7.37 psia,

15 in Hg=381 torr,

15 in Hg=50796 Pa.
