Question

Translation:
The ilustrated tube contains a liquid. On the left side of the tube, it is sealed ( the pressure on that side of the liquid is 0). On the right side it is open and the pressure on the liquid's surface is 1 atm. If the "h" is 2 meters, what is the liquid's density?

13. El tubo ilustrado a continuación contiene un liquido. El lado izquierdo está sellado al vacío (la presión sobre el líquido de ese lado es cero). El lado derecho está abierto, y la presión ahí sobre la superficie del liquido es 1 atm. Si la altura h es de 2 metros, podemos asegurar que la densidad del

Explanation / Answer

deltaP = rho g delta(H)

deltaP = Patm - P0 = 1 - 0 = 1 atm

= 101325 Pa

deltaH = 2 m

101325 = rho x 9.8 x 2

rho = 5170 kg / m^3
