Title: u-tube manometer; pressure
Post by: txxplc110 on November 16, 2020, 11:43:50 AM
Hello.
If the hydrostatic pressure in the tank is 100hPa and the external pressure is 1013hPa, then in the mercury u-tube manometer the level of manometric liquid will be:
1013hPa - 100hPa = 913hPa
913hPa = -684.8mmHg ("-" because external pressure is higher) (?)

Am I right?
