Fluid

Fluid is a substance that offers —- permanent resistance to deforming forces.

no

Fluid is a substance that offers no—— resistance to deforming forces.

permanent

the study of fluids has two parts, ——- and ——-

statics, dynamics

fluid—— concentrates on fluid at ——, while fluid—— concerns with the fluid in ——.

statics, rest, dynamics, motion

the study of the flow of liquid is called ——, whereas —— is the study of liquid at rest.

hydrodynamics, hydrostatic

____is either liquid or gas.

Fluid

the study of the ——- is called hydrodynamics, whereas hydrostatic is the study of ———.

flow of liquid, liquid at rest

a section on —— and ——-, which are important concepts of hydrostatic.

surface tension, capillarity

a section on surface tension and capillarity, which are important concepts of ———.

hydrostatic

the volume of a gas depends on —— and ——- obeying Boyle’s law and Charles’ law.

pressure, temperature

the volume of a —— depends on pressure and temperature obeying ——- law and ——- law.

gas, Boyle’s, Charles

the volume of a —— does not depend on pressure if the temperature is constant.

liquid

the volume of a liquid does not depend on —— if the ——- is constant.

Hence, the liquid is incompressible.

pressure, temperature

the —— is incompressible.

( the density of —- is constant for any pressure provided that ——— is kept constant.)

liquid, liquid, temperature

in the flow of fluids, the path or flow of the fluid particles is called ——-.

streamline

in the ————, the path or flow of the ——- particles is called streamline.

flow of fluids, fluid

incompressible

in Ideal laminar fluid flow, the flow has no —— or ——- is neglected.

friction, friction

in Ideal laminar fluid flow, the flow has no friction or friction is neglected. (——- friction in fluids is called ——-; and hence, ———-.)

Internal, viscosity, zero viscosity

the fluid flow is ——- (steady) and ——- flow is not taken into account.

laminar, turbulent
