Choose the wrong statement?

A The horizontal component of the hydro-static force on any surface is equal to the normal force on the vertical projection of the surface

B The horizontal component acts through the center of pressure for the vertical projection

C The vertical component of the hydrostatic force on any surface is equal to the weight of the volume of the liquid above the area

D he vertical component passes through the center of pressure of the volume

Review Detailed Answer

Correct Answer: he vertical component passes through the center of pressure of the volume

Choose the wrong statement ?

A any weight, floating or immersed in a liquid, is acted upon by a buoyant force

B Buoyant force is equal to the weight of the liquid displaced

C The point through which buoyant force acts, is called the center of buoyancy

D Center of buoyancy is located above the center of gravity of the displaced liquid v

Review Detailed Answer

Correct Answer: Center of buoyancy is located above the center of gravity of the displaced liquid v

Choose the wrong statement?

A Viscosity of a fluid is that property which determines the amount of its resistance to a shearing force

B Viscosity is due primarily to interaction between fluid molecules

C Viscosity of liquids decreases with in-crease in temperature

D Viscosity of liquids is appreciably affected by change in pressure

Review Detailed Answer

Correct Answer: Viscosity of liquids is appreciably affected by change in pressure

Choose the correct relationship ?

A specific gravity = gravity x density

B dynamicviscosity = kinematicviscosity x density

C gravity = specific gravity x density

D kinematicviscosity = dynamicviscosity x density

Review Detailed Answer
