A closed tank is filled with water and has a 4 -ft-diameter hemispherical dome as shown in Fig. 2.129. A U-tube manometer is connected to the tank. Determine the vertical force of the water on the dome if the differential manometer reading is \(7 \mathrm{ft}\) and the air pressure at the upper end of the manometer is \(12.6 \mathrm{psi}\).
