How can we determine whether the flow is laminar or turbulent?

The viscosity of a fluid in motion is 1 Poise. What will be its viscosity (in Poise) when the fluid is at rest?

What causes the cohesive forces acting at the free surface of a liquid?

An object with a specific gravity of 5 weighs 80 N in air. When it is fully immersed in water, its weight will be:

For which conditions is a reciprocating pump suitable?

To find the boundary layer thickness, which of the following parameters is required?

Oil in a hydraulic cylinder is compelled from an initial volume 2m³ to 1.96m³. If the pressure of oil in the cylinder changes from 70 MPa to 80 MPa during the compression, the bulk modulus of elasticity of oil (in MPa)is

In a laminar boundary layer flow over a flat plate, what would be the ratio of wall shear stresses τ₁ and τ₂ at the two sections which lie at distances x₁ = 20 cm and x₂ = 80 cm from the leading edge of the plate?

According to Archimedes' principle, if a body is immersed partially or fully in a fluid, the buoyancy force on the body is:

Water is coming out from a tap and falls vertically downwards. At the tap opening, the stream diameter is 20 mm with a uniform velocity of 2 m/s. Acceleration due to gravity is 9.81 m/s². Assuming steady, inviscid flow, constant atmospheric pressure everywhere and neglecting curvature and surface tension effects, the diameter in mm of the stream 0.5 m below the tap is approximately
