Hydraulics and Fluid Mechanics in ME A floating body is said to be in a state of stable equilibrium only when its centre of gravity is below its centre of buoyancy when the metacentre is above the centre of gravity when its metacentric height is zero when the metacentre is below the centre of gravity only when its centre of gravity is below its centre of buoyancy when the metacentre is above the centre of gravity when its metacentric height is zero when the metacentre is below the centre of gravity ANSWER DOWNLOAD EXAMIANS APP
Hydraulics and Fluid Mechanics in ME A compound pipe of diameter d1, d2 and d3 having lengths l1, l2 and l3 is to be replaced by an equivalent pipe of uniform diameter d and of the same length (l) as that of the compound pipe. The size of the equivalent pipe is given by l/d⁴ = (l₁/d₁⁴) + (l₂/d₂⁴) + (l₃/d₃⁴) l/d⁵ = (l₁/d₁⁵) + (l₂/d₂⁵) + (l₃/d₃⁵) l/d² = (l₁/d₁²) + (l₂/d₂²) + (l₃/d₃²) l/d³ = (l₁/d₁³) + (l₂/d₂³) + (l₃/d₃³) l/d⁴ = (l₁/d₁⁴) + (l₂/d₂⁴) + (l₃/d₃⁴) l/d⁵ = (l₁/d₁⁵) + (l₂/d₂⁵) + (l₃/d₃⁵) l/d² = (l₁/d₁²) + (l₂/d₂²) + (l₃/d₃²) l/d³ = (l₁/d₁³) + (l₂/d₂³) + (l₃/d₃³) ANSWER DOWNLOAD EXAMIANS APP
