1. A glass cylinder has a diameter of 17 cm. The water level in the cylinder is maintained at a constant height of 0.16 m. If the radius of the spout pipe is 0.57 cm, how high is the vertical stream of water? (Assume the water to be an ideal fluid.)

The density of water is approximately 1000 kg/m³.

2. A circular window of 24 cm diameter in a submarine can withstand a maximum force of 1.88 10⁶N. What is the maximum depth to which the submarine can go without damaging the window? _water =1000 kg/m³= 1 g/cm³

A 15,000 N vehicle is to be lifted by a 35 cm diameter hydraulic piston. What force needs to be applied to a 6 cm diameter piston to accomplish this?

A cylindrical rod of length 12 cm and diameter 2 cm floats in water. What is its mass?

Give the answer is gram.

_water =1000 kg/m³= 1 g/cm³

A wood cube 0.5 mon each side has a density of 720 kg/m³and floats levelly in water.What is the distance from the top of the wood to the water surface? Give the answer in meter.

The density of water is approximately 1000 kg/m³.
