The tool comes with a handful of templates for pallets with standard dimensions, weight and other parameters. You can customize the position in which your crates, cartons, boxes or other types of cargo are. When installing a loading coil of substantial inductance in an electrically short antenna, sheetmetal and dielectrics should be kept away from the coil and areas of antenna above the loading coil. This would include dielectrics on or near the inductor, since the presence of dielectrics would increase undesirable capacitance. When inductive reactance requirements are large, as when short thin. This designed load is expressed as a weight per square metre. Thus, using the formula of hold length x hold breadth x maximum tank top load in tonnes/m2 will give the maximum cargo that the vessel can load when spread evenly over the total tank top area. On bulk carriers the tank top area is often reduced by sloping hopper sides. There is no extra allowance made for hopper sides and this is not an area for compromise. The load arrived at by the above formula is always to be considered the.

A coil inductance formula is based upon the basic loop inductance. Inductance is the ability to store energy in a magnetic field, and coils are a very common way to create inductance. Many magnetic field coupling circuits, like chokes and transformers take advantage of a coil's magnetic storage properties. Wire Loop Inductance Descriptio To find out the loading your cartridge sees, use the following calculator. Phonostage: k, Turns Ratio: 1: , Loading = ohms So let's turn this around LOA is 120', with loading coils located at 42' from center. Coils are about 7 long x 4 3/16 diameter - 51 turns of wire yielding 143 uH each. Tails are 17'12. Design resonant freq. is 1.930 MH. Coils are about 7 long x 4 3/16 diameter - 51 turns of wire yielding 143 uH each If Q is known and the GPM is known, the required water delta T (LWT - EWT) can be calculated: Delta T (water) = Q / 500 * GPM Sensible and Latent Cooling The above equations for air do not apply to the majority of cooling coils (the equations for water apply to both heating and cooling coils).

Antenna Loading Coil Calculation - M0UK

This loading inductor is near the bottom of a 43-foot tall vertical. The top of the coil directly bonds to the upper vertical section with a jumper wire (hidden) on the far side of the plastic insulator. Shiny streamer marks on the surface of the plastic show where the intense electric field has caused corona or streamers. This vertical was operated at a kilowatt. Voltage was so high the edge of the metal washer produced corona streamers that etched the plastic The result is an allowable steel coil loading table which specifies under which circumstances certain coils can be carried safely. Optimizing the capacity When a ship is in motion, its vertical acceleration varies along the length of the cargo hold. Therefore the location of coils in the individual holds of a vessel must be accounted for when calculating loading tables. To optimize the coil. This calculator is a good guideline but uses the simple standard empirical formula for inductance of a single layer coil. That turned out to be something well under 250mm ( 10 ) when wound with 1.25mm wire closewound but I wanted a little more inductance to give me some flexibility. The calculated details below gave me up around 300uH so it was looking somewhat promising

The inductance required is based on the antennas total width (A), the distance from the center of the antenna to the loading coil (B), the wire diameter (D) of the radiating elements, and the required operating frequency (f). The equation for determining the inductance required is listed below. This web page eliminates the need for you to try and enter this messy equation in your calculator/computer. Note that the dimension C is the distance from the input of the Loading Coil to the end. Considering the minimum outdoor air requirement of 325 l/s this gives a value of 25% outdoor air and 75% recirculated. Coil capacity - A mix condition can now be found and the cooling coil sized. m x tm = (mr × tr) + (mo × to) 1.626 × tm = (0.75 × 1.626 × 20) + (0.25 × 1.626 × 28) tm = 22ºC The loading coil's Q is defined by the reactance of the inductor divided by the resisteance. Many factors affects a coil's Q. A silver wire winding on good isolation materal may produce a coil with Q ~= 250, an air based large diameter loading coil could have Q ~= 800. High Q loading coil will reduce the power loss in the loading coil, but also make it tuned sharply reduce the bandwidth the. Coil and transformer calculator.
