A 15 cm diameter piston is located within a which is connected to 1.3 cm diameter inclined tube manometer as shown cylinder in figure below. The fluid in the cylinder and the manometer is SAE 30 oil (specific 8.95 kN/m). If a weight W is weight = placed on the piston head, the fluid level in the manometer tube rises from point (A) to point (B), what will be the weight ? W Piston ** 30 (a) 1.188 N (c) 1.188 kN 15 cm A (b) 11.88 N (d) 11.88 kN B
