What does N1 mean on a calculator?

The magnetic flux through the loop is 0.098 Wb.

Magnetic flux (often symbolized Φ), is the measure or amount of magnetic field B passing through a certain cross-sectional area, for example, a coil of wire (this is also often called "magnetic field density"). The unit for magnetic flux in International Units is the weber (Wb) (Weber is a derived unit from the volt-second).

Magnetic Flux Formula:

                                   ∅ = B A cos α

Where:

∅ = magnetic flux (Wb)

B = magnetic field (T)

A = cross-sectional area (m)

α = angle between B and the normal plane

On the given question:

B = 0.50 T

r = 0.25 m

α = 0° ⇒ because it is in a flat plane

A = πr²

Then substitute:

∅ = B A cos α

∅ = 0.50 x π (0.25)² x cos0°

∅ = 0.50 x 3.14 (0.0625) x 1

∅ = 0.098 Wb

So that the magnetic flux bear is 0.098 Wb

where

the value of (m) is 1kg

the value of spring constant (k) is 164 n/m

let the value of [tex]\pi[/tex] is 3.14

Energy in terms of Joules = 1956.50 GJ is the answer.

Energy generation by the Power plant (on annual basis) is given as: -

A.  When heat recovery feature is Present

E = (M * HHV * C * ηc * 365) / 3600 watt – hr         ------------- equation (i)

B.  When heat recovery feature is not present

E = (M * LHV * C * ηc * 365) / 3600 watt – hr        ------------- equation (ii)

Here,

 M = Mass of Pellets consumed per day (Kg/day)

 HHV = Higher Heating Value of Biomass (J/Kg)

 LHV = Lower Heating Value of Biomass (J/Kg)

 C = Capacity factor {Plant running this % time in a day}

 ηc = Conversion efficiency

 Joule to watt – hr conversion factor

 1 Joule = 1 /3600 watt – hr

Given:

 M = 1.3 * 106 Kg/day;

 HHV = 19.9 * 106 J/Kg;

 LHV = 17.4 * 106 J/Kg

 C = 56% = 0.56

 ηc = 37% = 0.37

Heating Recovery feature ---> Present

As heating recovery feature is present so eq. 1 will be used

Now, putting corresponding given values in Eq. 1 to get the value of E.

E = (M * HHV * C * ηc * 365) / 3600

E = (1.3 * 106 * 19.9 * 106 * 0.56 * 0.37 * 365) / 3600

E = (1956.496 * 1012) / 3600

E = 543.47 Gwh

Energy in terms of Joules = 543.47 * 3600

Energy in terms of Joules = 1956.50 GJ

Energy Generation (E) by the power plant (on annual basis) = 543.47 Gwh (Giga Watt – hour)
