Problem: A vertical angle of -15°30' was measured to the top of an elevated water tank from an instrument set up on a hill 225.67m away. The height of instrument set up 1.22m above the ground whose elevation is 302.56m above sea level. If the height of the water tank above ground is 30.20m, determine the elevation of the base of the water tank considering the effect of earth's curvature and atmospheric refraction. Given: α = 15°30' (angle of depression) D = hor. Dist. = 425. 67m hi = 1.22m, ht. of instrument Ground elevation at the instrument set up= 302.56m Height of water tank = 30.20m Required: Elevation of the base of the water tank. Line of sight a V (vert. dist.) hi-1.22m Elev. 302.56m 30.20m Elevation of base Hor. Dist. - 425.67m
