##### A 6 -in.- -diameter piston is located within a cylinder that is connected to a $\frac{1}{2}$ -in.-diameter inclined-tube manometer as shown in Fig. P2.74. The fluid in the cylinder and the manometer is oil (specific weight $=59 \mathrm{lb} / \mathrm{ft}^{3}$ ). When a weight, $\%,$ is placed on the top of the cylinder, the fluid level in the manometer tube rises from point (1) to $(2) .$ How heavy is the weight? Assume that the change in position of the piston is negligible.
