How long should a laminar flow hood run before it can be used?
Laminar flow hoods and hepa filter must be certified every 6 months. The type of environment that a laminar flow hood provide ISO 5, which is formerly known as a Class 100 area.
Why must a circuit be closed in order for a current to flow?
A circuit must be closed in order for a current to flow because it helps keep a current flow pass. When the switch is closed on a circuit there is a constant flow. When the switches open the flow is disturbed around the circuit.
For electrons to flow continuously through a conductor there must be a?
A closed path.
In order to be considered a semi-conductor the material must?
easily accept electron flow.
If a food contact surface is in constant use how often must it be cleaned and sanitized?
Cooler shelves

What are the basic differences between laminar air flow and biosafety hood?
Do you know the difference between a laminar flow hood and a biological safety cabinet? Laminar Flow Hoods * provide product protection only and must not be used when working with any form of biohazard or chemical hazard * any potentially infectious aerosol that is created will lead to exposure of the operator and the environment * horizontal-flow clean-air bench used for cell cultures can expose the researcher to aerosols of allergenic or infectious materials. * vertical-flow clean-air bench also blows air out into the roomBiological Safety Cabinets * provide personnel and environmental protection and commonly product protection * infectious agents must be used in a biological safety cabinet NOT a laminar flow hood
When working in a horizontal laminar air flow hood you must work at least how many inches in from the outside edge of the work surface?
3 to 6
Why workstationmust cleaned?
why workstation must cleaned
When flowing gas flows from a larger diameter to a smaller diameter pipe?
The speed of the gas must increase. Also, depending on the geometry of the transition, it's comparatively difficult to maintain laminar flow, and there's typically considerable turbulence there and for some distance after.
Can you give me the word hood in a sentence?
You must be from the "hood".
Answer to howrse how often should a horse's stall be cleaned if the horse is in it frequently?
It must be cleaned daily.
After each use a non-mercury glass themometer must be cleaned and soaked in a?
the non-mercury glass thermometer must be cleaned and soaked in a in a -- after each use
What is bernoulli's basic theory?
The basic idea of the Bernoulli's Principle is very much related to the idea of conservation of energy. Bernoulli states that for laminar flow of an ideal fluid, the energy density (energy per volume) is constant. In other words, the state (magnitude) of an incompressible and non-viscous fluid that is undergoing laminar flow remains constant. Bernoulli explains that the sum of the magnitude of the fluid's pressure, kinetic energy density and potential energy density at a given time remains constant under stated conditions. Definition: Laminar flow is when at any given point, the velocity of the fluid particles is constant. This means that any particle passing a particular point of the motion does so at constant velocity. Laminar flow usually describes the movement of fluids moving at slow speeds. Using Bernoulli's Principle, we can understand how fluid will behave if even one of the conditions (pressure, kinetic energy density and potential energy density) change. For example, if the pressure increases compared to the previous state, the other factor(s) must be lowered in magnitude compared to the previous state since the energy density is constant.
Food contact surface must be cleaned and sanitized at least every how many hours?
Equipment must be CLEANED at least every 24 hours.

inside and out
Which item must be cleaned sanitized?
