In a hydraulic system the piston on the left has a diameter of 4.5 cm and a mass of 1.7 kg. The piston on the right has a diameter of 12 cm and a mass of 2.5 kg. If the density of the fluid is 750 kg/m3, what is the height difference h between the two pistons?(adsbygoogle = window.adsbygoogle || []).push({});

can someone please help me with this?

[tex]A_1 = (3.14)(0.045m/2)^2 = 0.000506m^2[/tex]

[tex]A_2 = (3.14)(0.12m/2)^2 = 0.0036m^2[/tex]

[tex]P_1 = mg/A_1 = (1.7kg)(9.8N/kg)/0.00506m^2 = 32924.9[/tex]

[tex]P_2 = mg/A_2 = (2.5kg)(9.8N/kg)/0.0036m^2 = 6805.56[/tex]

[tex]P_1 - P_2 = (\rho)(h)(g)[/tex]

[tex]h = (P_1 - P_2)/(\rho)(g)[/tex]

[tex]h = 3.55m[/tex]
