An ideal fluid flows through horizontal tube of variable diameter. The pressure is lowest where the
Correct answer: D. both a and b
- A. velocity is highest
- B. diameter is smallest
- C. diameter is largest
- D. both a and b
Explanation
According to Venturi relation "Where speed is high pressure will be low"So, option a) is correct. According to equation of continuity A2v1= A2v2. So, where the diameter is smallest the speed will be highest and pressure will be lowest . So, option b) is correct

About Fluid Dynamics
Fluid flow is described through speed, pressure and density, including steady flow and the equation of continuity for conserving mass. Bernoulli's equation relates pressure, speed and height, while fluid drag and terminal velocity explain why a falling object eventually moves at constant speed when drag balances its weight.
