- A ship whose hull length is 100 m is to travel at 10 m/sec. For dynamic similarity, at what velocity should a 1:25 model be towed through water ?
- For a sphere of radius 15 cm moving with a uniform velocity of 2 m/sec through a liquid of specific gravity 0.9 and dynamic viscosity 0.8 poise, the Reynolds number will be
- Free surface of a liquid behaves like a sheet and tends to contract to smallest possible area due to the
- The discharge over a broad crested weir is maximum when the depth of flow is (where H is the available head)
- The line of action of the buoyant force acts through the centroid of the
- Two pipe systems are said to be equivalent when
