When steady state reaches in the tank then?

a: The output velocity is always a constant Explanation

Explanation

b: The input velocity is always a constant Explanation

Explanation

c: The height of the fluid in the tank remains constant Explanation

Explanation

d: All of these Explanation

Explanation

An arrangement as in your experiment is at steady state, what will happen if you increase the output flow rate?

a: The fluid level in tank decreases continuously Explanation

Explanation

b: The fluid level in tank decreases and then becomes constant Explanation

Explanation

c: The fluid level in tank increases continuously Explanation

Explanation

d: The fluid level in tank increases and then becomes constant Explanation

Explanation

An arrangement as in your experiment is at steady state, what will happen if you decrease the input flow rate?

a: The fluid level in tank decreases continuously Explanation

Explanation

b: The fluid level in tank increases continuously Explanation

Explanation

c: The fluid level in tank decreases and then becomes constant Explanation

Explanation

d: The fluid level in tank increases and then becomes constant Explanation

Explanation

An arrangement as in your experiment is at steady state, what will happen if you increase the input first and then increase the output flow rate but by the same amount?

a: The height first increases and then decreases and reaches to it's original value Explanation

Explanation

b: The height first increases and then becomes constant but is more than the previous steady state's value Explanation

Explanation

c: The height first decreases and then increases and reaches to it's original value Explanation

Explanation

d: The height first decreases and then becomes constant but is less than the previous steady states value Explanation

Explanation

The steady state value of the height obtained as done practically is different from that calculated from equations with certain assumptions because

a: The value of inflow is not exactly equal to the value of the outflow Explanation

Explanation

b: There are fluctuations in the value of the inflow Explanation

Explanation

c: There is a problem of meniscus of the fluid which leads to misjudgement of the value obtained Explanation

Explanation

d: All of the above Explanation
