What is magnetomotive force formula?
Magnetomotive force (mmf), Fm = NI ampere-turns (At), where N = number of conductors (or turns) and I = current in amperes. Since ‘turns’ has no units, the SI unit of mmf is the ampere, but to avoid any possible confusion ‘ampere-turns’, (A t) are used in this chapter. 16. Magnetic field strength, or magnetising force.
What is flux per unit area?
Flux as flow rate per unit area. In transport phenomena (heat transfer, mass transfer and fluid dynamics), flux is defined as the rate of flow of a property per unit area, which has the dimensions [quantity]·[time]−1·[area]−1. The area is of the surface the property is flowing “through” or “across”.
What is Advective flux?
The advective flux refers to the movement of a compound along with flowing air or water. The advective flux density depends simply on concentration and flow velocity. In this course, we will generally define our coordinate system so that the x-axis is oriented in the direction of fluid flow.
What is the unit of flow rate Mcq?
Explanation: Mass flow rate = m/t, => unit = kg/s, volumetric flow rate = V/t, => unit = Liters/s, molar rate = n/t, => unit = moles/s.
What is unit for flow rate for gases * 1 point?
Gas mass flow rate is the actual mass of a gas which moves through a measurement instrument per unit of time. Its units are usually in standard liters per minute (slpm) or standard cubic centimeters per minute (sccm) in SI units. The most common English units include standard cubic feet per minute (scfm).
What precise movement does CMM have?
What precise movement does CMM have? Explanation: Co-ordinate measuring machines are useful for three dimensional measurements. These machines have precise movements in x,y and z coordinates which can be easily measured and controlled. 2.
Which type of CMM is most popular?
Bridge CMMs are the most common type of coordinate measuring machine.
How accurate is a CMM?
The accuracy of coordinate measurement machines are typically given as an uncertainty factor as a function over distance. For a CMM using a touch probe, this relates to the repeatability of the probe and the accuracy of the linear scales. 00005 inch (half a tenth) over the entire measurement volume.
