How much pressure does a rain drop have?
The pressure of a raindrop can vary based on its size and speed of descent, but typically it is around 10 times atmospheric pressure (around 1000 hPa). This pressure is spread out over the surface area of the raindrop, so it doesn't cause harm when it falls.
What is the relationship between the flow rate and the pressure drop across a pipe?
The relationship between flow rate and pressure drop across a pipe is that as the flow rate increases, the pressure drop also increases. This means that a higher flow rate will result in a greater pressure drop in the pipe.
Why pressure drops before storm comes?
Before a storm arrives, the pressure drops because the storm system's low-pressure center causes the air above it to rise, creating an area of lower pressure at the surface. As the storm approaches, the drop in pressure can be felt because our bodies are sensitive to changes in atmospheric pressure. This drop in pressure is often associated with unsettled weather and precipitation that accompany the storm.
How do you measure surface tension and what methods are commonly used for this measurement?
Surface tension is measured by determining the force required to break the surface of a liquid. Common methods for measuring surface tension include the drop weight method, the capillary rise method, and the maximum bubble pressure method.
How the speed of the particles that are able to escape from the surface of the drop?
The speed of particles that escape from the surface of a drop depends on the kinetic energy of the particles which is influenced by factors such as temperature and intermolecular forces. Higher temperatures and weaker intermolecular forces can increase the speed of particles escaping from the drop's surface.
How do molecules change the air pressure as you move away from the earths surface?
As you move away from the Earth's surface, the density of air molecules decreases, leading to a decrease in air pressure. At higher altitudes, there are fewer air molecules pushing down on a given area, causing the pressure to drop. This is why air pressure is lower at higher altitudes compared to sea level.
What can change from one state of matter to another at the temperature and pressure experienced at earths surface?
water changes from a liquid to a solid when you drop it below 32 F or 0 C. It also evaporates, changing into a gas in warmer weather.
How does surface roughness affect the pressure drop in a pipe if the flow is turbulent?
In turbulent flow, surface roughness significantly impacts pressure drop due to increased friction between the fluid and the pipe wall. Higher roughness elements disrupt the flow and create additional turbulence, leading to increased energy loss and higher pressure drop. The relationship is often quantified using the Darcy-Weisbach equation, where a rougher surface results in a higher friction factor, thus exacerbating the pressure drop across the pipe length. Consequently, engineers must consider surface roughness when designing piping systems to ensure efficient fluid transport.
Why is rotation?
You need to see a medical professional straight away. This could be caused by a drop in blood pressure or the blood pressure being too high.

How does air pressure drop?
Air pressure close to surface of the earth is 1 atmosphere. But as the altitude increases, air gets thinner in other words the molecules in air are farther than the one close to earth's surface. This causes the atmospheric pressure to decrease as we increase in altitude.
What Difference between the dry and wet column pressure drop at fixed flow conditions?
The dry column pressure drop refers to the pressure drop across the column when no liquid is present, while the wet column pressure drop refers to the pressure drop when the column is flooded with liquid. The wet column pressure drop is typically higher than the dry column pressure drop at fixed flow conditions because the presence of the liquid adds additional resistance to flow, increasing pressure drop.
When was Pressure Drop - song - created?
Pressure Drop - song - was created in 1970.
When was Pressure Drop - album - created?
Pressure Drop - album - was created in 1975-11.
What is mean by pressure drop how can you measure the pressure drop?
Use a delta-p gauge
Do the pipline losses reduce after the pipeline are in use for 1 year or so?
No. The pressure drop remains the same. The only thing that could led to a smaller pressure drop after 1 (or more) year, is the internal surface friction coefficient. But this coefficient does not change in a measurable way. Perhaps small particles are re-arranged inside the pipe, but the coefficient remains the same. So does pressure drop.
