If a fluid of certain surface tension and diameter is used to create a...
Explanation: For soap bubble,
P=8*σ/d
For liquid jet,
P=2*σ/d
Hence, soap bubble will be having more pressure difference.
P=8*σ/d
For liquid jet,
P=2*σ/d
Hence, soap bubble will be having more pressure difference.

Explanation:
Surface Tension:
Surface tension is the property of a liquid that allows it to resist an external force due to the cohesive nature of its molecules. It is responsible for the formation of soap bubbles and liquid jets.
Soap Bubble:
A soap bubble is formed when a film of liquid is surrounded by air or another gas. The surface tension of the liquid causes the film to form a spherical shape, with the pressure inside the bubble being slightly greater than the pressure outside.
Liquid Jet:
A liquid jet is formed when a high-speed stream of liquid is ejected from a small orifice. The surface tension of the liquid helps to maintain the integrity of the jet, keeping it intact as it travels through the air.
Pressure Difference:
The pressure difference between the inside and outside of a soap bubble or a liquid jet is due to the surface tension of the liquid. The surface tension acts to decrease the pressure inside the bubble or jet, causing the pressure inside to be lower than the pressure outside.
Comparison:
In the case of a soap bubble, the pressure inside the bubble is greater than the pressure outside, but only slightly. This is because the surface tension of the liquid film is trying to contract and minimize its surface area, resulting in a slightly higher pressure inside the bubble.
On the other hand, in the case of a liquid jet, the pressure inside the jet is significantly lower than the pressure outside. This is because the liquid is being accelerated as it flows through the small orifice, resulting in a decrease in pressure according to Bernoulli's principle. Additionally, the surface tension of the liquid helps to maintain the integrity of the jet, preventing it from breaking up or dispersing.
Conclusion:
Therefore, the soap bubble will have a greater pressure difference on the inside and outside compared to the liquid jet. The pressure inside the bubble is slightly greater than the outside, while the pressure inside the liquid jet is significantly lower than the outside.
