I am about to start renovating a dormer bungalow and want to add bath/shower on upper floor.Cold storage in attic with hot storage on upper floor. Currently no outlets upstairs so can`t fit gauge to measure pressure. Anyone know a mathematical formula for calculating likely pressure in gravity fed system based on head of water. This is a rural situation with private water supply therefore normal mains pressure is not an option.
As an "Old-Grey", educated in the era of O-LEVELS, we were taught that one atmosphere of pressure= 14.5 psi,= 760 mm mercury on a barometer, = 32 feet of water-gauge (head from a raised tank). This is the basis of one BAR, measure you see on weather-charts, and the millibar, which is one thousandth of an atmosphere of pressure.
Pascals and newtons did not complicate my life until I went to Uni., just at the same time as nanometres and picometres supplanted angstrom units !!
I hate metrication and all other arbitrary obsolescence, and still remember the confusion old folk experienced when our coinage was decimalised --- home-helps were suspected to be theives.
Heaven help us if we get the Euro.
