In your house (elevation 500 ft) you have a barometer thatregisters inches of mercury. On an average day in January, youtelephone the weather station (elevation 700 ft) and are told thatthe exact pressure there is .966 bar. What is the correct readingfor you barometer and to how many psia does this correspond? Thespecific gravity of mercury is13.57. Help please! I'm not interested in the actually value, I just want to knowwhat the procedure is to obtain the correct answer. In your house (elevation 500 ft) you have a barometer thatregisters inches of mercury.

Explanation / Answer
P500 = P700 +air*g*h P700 = 966bar g = gravity P500 = P700 + air*g*(700-500) convert units of pressure to fit desired solution P500 = spgrHg*g*hHg hHg =(P500/spgrHg*g)
