1. A vertical triangular area with vertex downward and altitude 'h' has its base lying on the free surface of a liquid. The center of pressure below the free surface is at a distance of h/2.

2. The increase in metacentric height increases stability.

3. If a vessel containing liquid moves downward with a constant acceleration equal to 'g', then pressure throughout the liquid mass is atmospheric. 

4. Magnitude of the component of velocity at point (1,1) for a stream function U= x^2- y^2 is equal to 2*(2)^1/2.

5. A fluid jet discharging from a 4 cm diameter orifice has a diameter of 3 cm at its vena-contracta. If the co-efficient of velocity is 0.98, the coefficient of discharge for the orifice will be 0.98*0.75^2.
