How to Calculate your Heater Wattage (Get your target temperature)

[@blender_unleashed]

So difficult to find info on the internet these days. You really helped me

[@Presso99]

can you please open up a subject on the design of heating coil for roaster?

[@dominiksavli3285]

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.

[@kevinnazeraj1799]

Exactly because kw=power=kjouls/s

Brother, i have a lithium ion lfp battery in ABS container size 25.2 x 26.5 x 27 cm with 0.6 cm thickness with exact lid with 0.8 cm thickness. Weigh of container is 2.91 kg.. how to calculate the heater pad wattage to bring -40 deg c temp to 0 deg c, pls help

I need to heat water with mch heaters but there is a problem i don't understand that how much power i have to give to it

[@mehreenkanwal2170]

very good way of explanation,,, can you plz guide to any video or link for calculating time needed to heat metal from 20 celcius to 100 celcius, 50mm sqaure aluminum pipe, 2mm wall thickness,, 1 meter long,, in closed chamber or oven (lhw 1,5 x 0,25 x 0,25m), having constant heat source, 100 watts heating element,, and some air circulation.

[@travellingwithvagabond8688]

What will be the solution for -20 C and for 8000 meter lenght pipe line?

[@rajbirsaini9838]

Good bro i know it already because, i am furnace manufacturer

[@carljustinepadlan7368]

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]

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.

[@aliasger.kalolwala]

hey i am unaware of the BTU conversion for the specific heat of aluminium that you used. The aluminum i am using has a Cp of 714.8J/kg.K and deltaT is 110C and 1hr heating time....can you please help with this?

[@donnymontreano2045]

convert the delta celcius into Kelvin

[@seniordesign3830]

I want to heat a nichrome coil so I can boil water, I want it to reach 200 C degree in a minute Can I use your equation to know how much power do I need ???

[@naveenkumarful]

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

[@DwyerOmega]

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.

[@mubashirislam2791]

I want to make heaters for my plastic extruder Bailer dia 23.5 inches Where my starting temp 30 °c And required temperature 300°C Applied voltages 440 v ac Which no of wire I can use and how long plz tell me

[@DwyerOmega]

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

[@robertogabriel6430]

Very good, thank You!!!

[@mayneac]

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?

[@mayneac]

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).

How to calculate the wattage required to heat a tank containing liquid at a given temperature?

[@donnymontreano2045]

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

[@josephsun7783]

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

[@nikpik9584]

the second one

[@stevequate1797]

Still can’t figure it out, I’m stupid I guess, I just need to know how hot a silicon rubber mat 3/6” thick with heater element wound throughout the mat 2”x 5” 120v and 50 watts, the average temp of inside house is 68 degrees, don’t know everything you need to figure out problem thanks I’ll keep searching

[@axelateon1384]

yeah you are totally stupid

[@astrofamily6081]

Weight or Mass?

[@hussamridan7872]

In the case of muffle furnace What should the weight of material and specific heat be ? Please i need a help

[@DwyerOmega]

Hello Hussam, thanks for your question! In the case of a muffle furnace, you would use the Free Air Heating Equation: Kw = (SCFM x Temperature Rise °F)/3000

[@ganeshlokare1552]

How you selected conversation factor?

[@DwyerOmega]

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

[@deitmagnet947]

@@DwyerOmega isn't it BTU be converted to kilojoules? And watts is a unit of power wherein it's in J/s

[@SalmanAnsari-ce6nx]

Hello sir i need your help

[@NIRVANA_1182]

I fucking love you dude

[@sandeepjatin1593]

Sir furnace ka kw and heater sulection

[@thesciencefurry]

OMG That's exactly what I need! thx

[@lambajilamba802]

In closed vessel medium air formula???

[@DwyerOmega]

Thank you for your inquiry! We have our generic air flow formula: kilowatts = SCFM x (Target - Starting Temperature °F) / 3000 If you need more information, call or chat online at omega.com and speak with one of our Application Engineers.

[@pratheeshtom4758]

I CALCULATED MANY TIMES IN DIFFERENT CONFIGURATION ALSO INCLUDING YOUR EQUATION ITS WRONG AND PLEASE REVISE

[@wilsonraj8770]

No audio re record it

[@jimh6189]

LOL He conveniently uses 1 hour heat up time so his error does not show up in the calculation. Someone is playing a joke on you - to the detriment of the company. Don't blame this guy- he's just an actor.

[@axelateon1384]

lmao

[@taboosaboo]

3412?

[@MariaHernandez-ml3tq]

It's a conversion Factor, BTU/kWh

[@muchlisrifai2831]

NOICE

[@jimh6189]

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.
