Hydro statics Problem. In the system shown in the picture, a multi fluid manometer measures the air pressure in a tank of an unknown liquid. In the tank, a spherical float of radius r is positively buoyant on a line with tension T. Using the parameters given, calculate the gauge pressures at G1, G2 and G3 and the density of the unknown liquid. Assuming the density of mercury to be 13500 kg/m^3, oil to be 960 kg/m^3 and gravity as 10 m/s^2

H1 = 29 cm

H2 = 18 cm

H3 = 14 cm 

H4 = 1.7 m 

H5 = 1.3 m  

T = 360 N

r = 10 cm
