This is due to earths location in the solar system. Earth is in the habitat zone or the Goldie locks zone, in this zone it's not too hot or not too cold for water to exist. Other planets in different star systems have liquid oceans due to them being in the habitat zone.

A vacuum gage attached to a power plant condenser gives a reading of 27.86 in. of mercury. The surrounding atmospheric pressure

Nadusha1986 [10]

Answer:

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

$p = \rho gh$

$p = 848 \ lb/ft^3 * 32 \ ft/s^2 *2.32 ft = 62955.52 \ lbft/s^2 * 1/ft^2$

we know that $1\ lb ft\s^2 = \frac{1}{32.174}\ lbft$

1 ft = 12 inch

therefore $p = 62955.52 * \frac{1}{32.174} * \frac{1}{12^2}\ lbf/in^2$

$p = 13.59\ lbft/in^2$

$P_{atm} = 14.66\ lbf/in^2$

so absolute pressure = $P_{atm} - p$

= 14.66 - 13.59 = 1.07 lbft/in^2
