In which one of the following cases will the liquid flow in a pipe be most streamlined

View answer and explanation

Correct option: B

Liquid of high viscosity and low density flowing through a pipe of small radius

Option B (Liquid of high viscosity and low density flowing through a pipe of small radius) is correct because streamline flow is favored by high viscosity, low density, and small pipe radius, as indicated by a low Reynolds number.

poise. A liquid rises to a height of 2 cm in a capillary tube. The angle of contact between the solid and the liquid is zero. The tube is depressed more so that the top of capillary tube is only one cm above the liquid. Then the apparent angle of contact between the solid and liquid is An object weights
