Test: Fluid Flow Methods & Types - Question 3

In unsteady flow, the flow parameters change with respect to position.

Detailed Solution for Test: Fluid Flow Methods & Types - Question 3

Explanation: In unsteady flow, the flow parameters change with respect to time.

Test: Fluid Flow Methods & Types - Question 4

 Uniform flow is defined as the type of flow in which acceleration is zero i.e velocity is constant.

Detailed Solution for Test: Fluid Flow Methods & Types - Question 4

Explanation: Uniform flow is defined as the type of flow in which the velocity does not change with respect to space. It can change with respect to time.

Test: Fluid Flow Methods & Types - Question 5

In laminar flow fluid particles flow along a streamline.

Detailed Solution for Test: Fluid Flow Methods & Types - Question 5

Explanation: As per the definition of laminar flow, fluid particles flow in a streamlined manner.

Test: Fluid Flow Methods & Types - Question 6

 Eddies formed in the turbulent flow are major cause of the energy loss in the turbulent flow.

Detailed Solution for Test: Fluid Flow Methods & Types - Question 6

Explanation: Due to zig zag motion of particles eddies are formed and they lead to energy losses.

Test: Fluid Flow Methods & Types - Question 7

 For compressible flow specific gravity remains same. 

Detailed Solution for Test: Fluid Flow Methods & Types - Question 7

Explanation: For compressible flow, density changes and therefore specific gravity changes.

Test: Fluid Flow Methods & Types - Question 8

When the flow particles flow in zigzag manner and rotate about their own axis it is what type of flow?

Detailed Solution for Test: Fluid Flow Methods & Types - Question 8

Explanation: It is random manner of fluid flow.

Test: Fluid Flow Methods & Types - Question 9

If the velocity is function of two space coordinates along with time then fluid flow is three dimensional in nature.

Detailed Solution for Test: Fluid Flow Methods & Types - Question 9

Explanation: If the velocity is function of two space coordinates along with time then fluid flow is three dimensional in nature.

Test: Fluid Flow Methods & Types - Question 10

 What is unit for flow rate for gases?

Detailed Solution for Test: Fluid Flow Methods & Types - Question 10

Explanation: Unit for flow rate for gases is Newtons/s or kgf/s.
