Question # 1

In deriving the Bernoulli's equation, we assume that the fluid is

Choose an answer

incompressible

no viscous

flows in a steady manner

all of them

The pressure will change in the pipe, as the fluid moves through that pipe of varying

Choose an answer

cross-section

height

none of them

both of them

If the flow is incompressible and the flow is steady then the mass of the fluid through the pipe

Choose an answer

increases

decreases

becomes zero

is conserved

In case of streamed lined flow of liquid, the loss of energy is

Choose an answer

Maximum

Minimum

Infinite

equal to what is in turbulent flow

Pressure exerted by a gas on the walls of its container in due to

Choose an answer

adhesion between the gas molecules and the container

cohesion between the gas molecules and the container

collision between the gas molecules and the container

surface tension of the gas

The body will move with terminal velocity when it acquires

Choose an answer

minimum speed

zero speed

maximum speed

none of them

According to the Bernoulli's equation, where the speed of the fluid is high, the pressure will be

Choose an answer

low

zero

high

all of them
