What is the equation for inward pressure?

• A. Inward pressure formula
• B. Portable eductors
• C. External pressure
• D. Internal pressure

Answer: (B)

Inward pressure is created by a device that generates suction to pull fluids and air into a system. A portable eductor does this by using a high-velocity jet to entrain surrounding fluid, which lowers the pressure at the eductor’s inlet and causes air or water to flow inward toward the pump or collection point. That ability to produce a negative pressure or suction inside a space is why portable eductors are the device used to establish inward pressure. The other choices either name a type of pressure or a generic formula rather than a method to create the inward pressure itself.
