Which of the following statement is wrong?a)A flow whose streamline is...
Yes, that is correct. The statement "The length of divergent portion in a venturimeter is equal to the convergent portion" is incorrect.
A venturimeter is an instrument used to measure the flow rate of a fluid in a pipe. It consists of a convergent section and a divergent section, with a throat in between. The convergent section is designed to accelerate the flow of the fluid, while the divergent section is designed to decelerate the flow.
The convergent and divergent sections of a venturimeter are typically of different lengths, with the convergent section being shorter than the divergent section. This helps to ensure that the flow is properly accelerated and decelerated as it passes through the instrument.
So, the correct answer is:
c) The length of divergent portion in a venturimeter is equal to the convergent portion.

Which of the following statement is wrong?a)A flow whose streamline is...
The wrong statement is option 'C', which states that the length of the divergent portion in a venturimeter is equal to the convergent portion.
Explanation:
A venturimeter is a flow measurement device that works based on the principle of Bernoulli's equation. It consists of a convergent section, a throat, and a divergent section. The convergent section narrows down the flow area, causing the velocity of the fluid to increase and the pressure to decrease. At the throat, the flow reaches its maximum velocity and minimum pressure. Finally, in the divergent section, the flow area increases, causing the velocity to decrease and the pressure to increase again.
The correct statement should be that the length of the divergent portion in a venturimeter is not equal to the convergent portion. In fact, the divergent portion is typically longer than the convergent portion. This design ensures that the pressure recovery occurs gradually, allowing the flow to regain some of its pressure energy. If the divergent section was equal to the convergent section or shorter, the pressure recovery would be abrupt, causing a loss of energy and inaccurate flow measurement.
The length of the divergent section is designed based on the desired pressure recovery and the specific application requirements. It is typically longer to provide a smooth transition and minimize energy losses. The length of the convergent section is also carefully designed to achieve the desired flow acceleration and pressure drop.
In summary, the length of the divergent portion in a venturimeter is not equal to the convergent portion. The divergent section is usually longer to ensure gradual pressure recovery and minimize energy losses.
