Hydrokinematics - Short Questions & Answers

Hydrokinematics - Short Questions & Answers Points :Hydrokinematics Short Questions & Answers Q.1: Define the term hydrokinematics. Ans: Hydrokinematics deals with the study of velocity and acceleration of the liquid particles without taking into consideration any force or energy. Q.2: Define the term date of discharge. Ans: The quantity of a liquid, flowing per second through a section of a pipe or a channel is known as the rate of discharge. Q.3: Write down the units of discharge. Ans: m³/sec and ft³/sec Q.4: Write down the formula of discharge. Ans: Q = A x V
A = Area
V = velocity Q.5: Define the term equation of continuity of a liquid flow. Ans. If an incompressible liquid is continuously flow through a pipe or a channel the quantity of liquid passing per second is the same at all section. This is known as the equation of continuity of a liquid flow. Q₁ = Q₂ = Q₃ ________ Q.6: Find the discharge. Water flowing through a pipe of 100 mm diameter with the average velocity of 10m/sec.

Q.7: Define the term path lines. Ans: The path followed by a fluid particle in motion is called a path line. Q.8: Define the term stream line. Ans: The imaginary line, drawn in the fluid in such a way that the tangent to any point gives the direction of motion at the point is called the stream line. Q.9: Define the flow Net, Ans: The relation between streamlines and potential lines drawn both the lines for a flow, the pattern obtained by the inter section nf two sets of lines is called flow net. Q.1O: What Is uniform flow? Ans: A flow in which the velocities of liquid particles at all sections of a pipe or channel are equal is called a uniform flow.
