can you please open up a subject on the design of heating coil for roaster?
@dominiksavli32854 жыл бұрын
Well, it gives somehow the right idea, but it should be devided by time, not multiplied by time. Either that or correct use of parenthesis is required to repair your equation.

What if Im gonna calculate for the wattage of a liquid chemical. Do I need to calculate for the volume of the tank not the weight.
@DwyerOmega Жыл бұрын
For this you will need to use the formula Q = m*c*∆T. Q (joules); m (mass of chemical); c (specific heat of chemical); ∆T (change in temperature °C). Then convert joules to watts.

Hi, I want to calculate kw for a tempering furnace, where my load is 250 Kg, material is iron, max temp 660 deg, soaking time 120 min Please suggest
@DwyerOmega4 жыл бұрын
Thank you for your inquiry. You still need to know your Starting Temperature to get your Delta Temp°F (Target (660°) - Starting (?°F). Iron has a specific heat of 0.108 Btu/lb°F. Use the same equation shown in the video.

@DwyerOmega2 жыл бұрын
Hello and thanks for your question! It depends on the wattage rating for the heater you are building. Wire gauges have ampere limitations that can be found in the table on this data sheet from Omega: assets.omega.com/pdf/cable-and-wire/heating-wire/NI80.pdf
@robertogabriel64304 жыл бұрын

@mayneac8 ай бұрын
Based on your formula heater wattage increases with increased heat up time? Should it not be the opposite? More power would heat up the same volume faster, not slower?
@mayneac8 ай бұрын
Finally figured it out despite your application engineer refusing to help - the second half of the equation is missing a parentheses, duration (h) should be in the denominator as well).

@donnymontreano20452 жыл бұрын
Water = 1 kg CP = 1.001 BTU/lb F Delta temp = 78F - 100F= 22F Hour = 1 ((1 x 1.001 x 22F)/3412) x 1 hour = 6.45 watt

the correct formula should be Kw= (5.0X0.21X90)/(3421X1), or (5.0X0.21X90)/3421/1

@DwyerOmega4 жыл бұрын
Thank you for your inquiry. The conversion factor is used because kilowatt-hour is a standard unit of electricity production and consumption. However the relationship between the kilowatt-hour and the BTU depends on which "BTU" is used. It is common, but not universal, to use: 1 kWh = 3412 BTU

What about heat loss? I think this equation (the equation he is trying to make) is based on a perfectly insulated system with no heat loss. Surely on a cold day it's going to take much more heat than this. This really gives a bad name for "Engineering" especially when "Omega" is attached. I think the 95 "Thumbs up" are from Omega employees. I would check other sources before I trusted any information from this (Omega) site.
