i dont have the density

just answer omg

Exercise 1: Calculate clearly and precisely on the following with much details As shown in Figure below, the U tube mercury manometer is used to measure the pressure p5 within a sealed tank. Now we know the positions z1=2.4m, z2 =0.3m, z3 =1.8m, 24 =0.5m, z5 =3.0m. Please give the hydrostatic equilibrium equation and calculate p5 P. 5 Ps 5 1 3 3 4 4 2 || 2
