Un manómetro se usa para medir la presión en un recipiente. El fluido que se emplea tiene una densidad relativa de . Y la altura de la columna del manómetro es de . Si la presión atmosférica local es de , determine la presión absoluta dentro del recipiente.

P =

Explanation:

For this exercise we use that the pressure at a given level is the same, so we set a level on both sides of the pressure gauge, just the point where the liquid is on the system side, with a pressure (P)

           P =

where is the atmospheric pressure in pascals, ρ the density of the liquid, g is related to gravity and h the height of the liquid from the marked reference.

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .
