Active pressure is the lateral pressure exerted by the soil on a retaining wall or structure. It occurs when the soil is compacted or dense and is prone to pushing against the wall or structure. Active pressure increases with the height of the wall or structure and the angle of repose of the soil.

If the temperature of a fixed amount of gas is increased at a constant pressure what will happen to a volume?
Volume will increase. Think of it this way. If you heat a gas, it gets hotter. When a gas gets hotter, the atoms/molecules are "more active" and the pressure and/or the volume will go up. If your experiment with heating this gas sample must have a constant pressure, then volume will have to increase to give all those "more active" atoms/molecules more play room to prevent the pressure from going up.
Which is true about intrapulmonary pressure and intrapleural pressure?
Intrapulmonary pressure is the pressure inside the lung alveoli, while intrapleural pressure is the pressure in the pleural cavity. During normal breathing, intrapleural pressure is lower than intrapulmonary pressure, creating a pressure gradient that helps keep the lungs inflated.
Can static pressure be converted to velocity pressure?
Yes, static pressure can be converted to velocity pressure through the Bernoulli's equation, which relates total pressure to the sum of static pressure and dynamic pressure (velocity pressure). In a flow system, the dynamic pressure represents the kinetic energy of the fluid due to its velocity, while static pressure is the pressure exerted by the fluid when it is at rest.
What is the Difference between Dynamic pressure and static pressure?
Dynamic pressure is the pressure exerted by a fluid in motion, caused by its velocity, while static pressure is the pressure exerted by a fluid at rest. Dynamic pressure increases with the square of the velocity, whereas static pressure remains constant regardless of velocity.
If a gas has an absolute pressure of 319 kPa its gage pressure is?
The gauge pressure is the absolute pressure minus atmospheric pressure. If atmospheric pressure is considered to be 101 kPa, then the gauge pressure would be 219 kPa.
What are in active volcanoes?
gases,pressure,magma
What is the Difference between an active earth pressure and passive earth pressure?
When the wall moves away from the backfill, the earth pressure on the wall decreases. This minimum pressure is called active earth pressure. On the other hand if the wall moves towards the backfill, the earth pressure increases. This maximum pressure is called passive earth pressure.
How many pressure groups are active in the UK?
Over 7000 pressure groups are thought to operate in the UK.
What is the pressure to be sexually active?
there is no pressure you do it when youre ready if youre asking if it hurts yes but if i were you i wuld wait.
What are the three agents of metamorphism?
The three agents of metamorphism are heat, pressure, and chemically active fluids. Heat causes recrystallization of minerals, pressure can deform rocks, and chemically active fluids can alter the mineral composition of rocks.
The three agents of metamorphism are?
The three agents of metamorphism are heat, pressure, and chemically active fluids. Heat is responsible for increasing temperature, pressure for increasing stress and confining pressure, and chemically active fluids for introducing new minerals through the process of metamorphism.
Why passive earth pressure is greater than active earth pressure?
The passive earth pressure occurs when when a wall or plane moves towards earth. This will create additional pressure where as in the case of active pressure wall moves away from earth and it will reduce the pressure on the wall. From the co-efficient of active earthpressure and passive earthpressure,i.e Ka = 1-sin( phi)/1+sin( phi) Kp = 1+sin( phi)/1-sin( phi where phi is the angle of internal friction of soil.
What is the Significance of atmospheric pressure?
The atmospheric pressure plays a huge role when determining the weather. If the pressure is high, winds will be more active.
What active ingredients are found in 7 up?
Carbon dioxide under pressure
What are three main agents of metamorphism?
Heat, Pressure, and Chemically active fluids.
What is the average blood pressure for an active 37 year old male?
136/76
What are some situations where the pressure potential is less than zero?
In an active vacuum environment.
