What’s the saying “get a life”

Things you do to amuse yourself on a cold wet afternoon.
The brine header tank for the a/c plant was about a third of the way up the funnel on the Himalaya. It had to be above the a/c unit for the Captains accommodation and I estimated that was about 120 ft above the a/c aft fridge flat. From memory I thought the Brine Head Gauge use to read about 60 psi.

Assuming calcium chloride brine at a density of 1200 kg/m3, gravity 9.81m/s and height in m and the SI formula below to calculate the pressure then:

P = ρ g h P = N/m2 ρ = 1200 kg/m3 g = 9.81 m/s

h = 120ft x 0.3048 = 36.576 m

P = 1200 x 9.81 x 36.576 = 430572.7 N/m2 ÷ 100000 = 4.31 bar x14.5 = 62.495 psi

The forward fridge flat had a brine head gauge reading of about 35 psi

35 ÷ 14.5 = 2.414 bar x 100000 = 241400 N/m2.. Rearranging the formula, then :

h = P/ ρ g

241400/ 1200 x 9.81 = 20.506 m /0.3048 = 67.277 ft above the fridge flat, but where? that I’m afraid escapes me after 56 years.
