Why the effect of leakage of water at the pipe joints on the pressure?
Leakage of water at pipe joints can reduce the pressure in the system because it allows water to escape before it reaches its intended destination. This means the force propelling the water through the pipe is reduced, leading to a drop in pressure. Additionally, the leakage creates inefficiencies in the system, requiring more energy to maintain the desired pressure levels.
Does there occur any change in melting point of ice by variation of pressure?
Yes, increase in pressure causes the freezing point to drop.
How do you calculate maximum allowable pressure drop in pipe during hydrotest?
To calculate the maximum allowable pressure drop during a hydrotest, you first determine the pipe's allowable stress and the hydrostatic test pressure, which is typically 1.5 times the design pressure. The allowable pressure drop can then be assessed using the formula: ( \Delta P = \frac{2 \cdot (S \cdot t)}{D} ), where ( S ) is the allowable stress, ( t ) is the wall thickness, and ( D ) is the pipe diameter. Ensure the drop does not exceed industry standards and safety regulations. Always consult relevant codes and standards for specific guidance.
What is going to happened when a balloon is filled with helium and is left in a car over night temperature drop 20 degrees?
Its volume will be reduced so it will be deflated. As long as there is no leakage, this is due to the fact that the drop in temperature reduces the kinetic energy of the gas atoms, which decreases the collisions between them and the sides of the balloon, which will cause a reduction in the pressure. As long as there is no leakage of the gas, the helium balloon will re-inflate when the temperature increases.
What are some common fluid mechanics problems and solutions related to pressure?
Common fluid mechanics problems related to pressure include calculating the pressure difference between two points in a fluid, determining the pressure at a specific depth in a fluid, and analyzing the pressure drop in a pipe system. Solutions involve using Bernoulli's equation, the hydrostatic pressure formula, and the Darcy-Weisbach equation to calculate pressure values and understand fluid behavior.
When was Pressure Drop - song - created?
Pressure Drop - song - was created in 1970.
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.
What is mean by pressure drop how can you measure the pressure drop?
Use a delta-p gauge
When was Pressure Drop - album - created?
Pressure Drop - album - was created in 1975-11.
In which part of the circulatory system does the greatest pressure drop occur?
The greatest pressure drop in the circulatory system occurs in the arterioles. Arterioles are small, muscular blood vessels that regulate blood flow and control blood pressure. As blood travels from the arteries to the capillaries, the arterioles cause a significant decrease in pressure to ensure proper exchange of nutrients and waste between the blood and tissues.
Why do you have variation in leakage reactance of induction motor?
leakage reactance in induction motor depends on the reluctance of the path in which the leakage flux is establishing. with the increase in stator current the leakage flux also increases but it cannot maintain linear relationship because of saturation of the leakage flux path, even though current is increasing the flux will not increase and it'll be constant after saturation. this leakage flux links with the stator winding and induces emf which will be opposite to the supply voltage causes drop in applied voltage , the drop in the applied voltage is represented with the leakage reactance. as flux is responsible for the induction of emf , the increase in current does not increase flux after saturation and therefore emf also doesnot increase so the leakage reactance is not constant throughout the machine operation...
