The device shown is the buoyancy measurement device used to measure the liquid height change. A pressure sensor is installed at the bottom of the tank, and a force sensor is installed to measure the upward force on the horizontal lever. The distances to the pivot point from the force sensor and cylinder are X1 and X2, respectively. The reference pressure at the reference liquid height, h0, to the bottom of the cylinder is pref. (4) If the force measured by the force sensor is Fsensor = 7.53 N, X1 = 1.58 m, X2 = 0.17 m, the diameter of the cylinder is D = 0.05 m, and the specific weight of the liquid is γf = 8.70 kN/m3, calculate the liquid height difference, Δh, relative to the reference height h0. __________ m.
