Formula for calculating btu for a room metric?
Calculating your air conditioning requirementsHeat LoadThe amount of heat generated is known as the heat gain or heat load. Heat is measured in either British Thermal Units (BTU) or Kilowatts (KW). 1KW is equivalent to 3412BTUs.The heat load depends on a number of factors, by taking into account those that apply in your circumstances and adding them together a reasonably accurate measure of the total heat can be calculated.Factors include:The floor area of the roomThe size and position of windows, and whether they have blinds or shadesThe number of room occupants (if any)The heat generated by equipmentThe heat generated by lightingFloor Area of RoomThe amount of cooling required depends on the area of the room. To calculate the area in square metres:Room Area BTU = Length (m) x Width (m) x 337Window Size and PositionIf, your room has no windows, you can ignore this part of the calculation. If, however there are windows you need to take the size and orientation into account.South Window BTU = South Facing window Length (m) x Width (m) x 870North Window BTU = North Facing windows Length (m) x Width (m) x 165If there are no blinds on the windows multiply the result(s) by 1.5.Add together all the BTUs for the windows.Windows BTU = South Window(s) BTU + North Window(s) BTUOccupantsYou will have to take that into account people who normally working in the space. The heat output is around 400 BTU per person.Total Occupant BTU = Number of occupants x 400EquipmentClearly most heat in a room is generated by the equipment. This is trickier to calculate that you might think. The wattage on equipment is the maximum power consumption rating, the actual power consumed may be less. However it is probably safer to overestimate the wattage than underestimate it.Equipment BTU = Total wattage for all equipment x 3.5LightingTake the total wattage of the lighting and multiply by 4.25.Lighting BTU = Total wattage for all lighting x 4.25Total Cooling RequiredAdd all the BTUs together.Total Heat Load = Room Area BTU + Windows BTU + Total Occupant BTU + Equipment BTU + Lighting BTUThis is the amount of cooling required so you need one or more air conditioning units to handle that amount of heat.
How many type of earthing?
Five types of earthing systems are there..They are as TT system, IT system, TN-S system, TN-C-S system, TN-C system
What is the interlace in pole and zero?
its nothing but alternate occurence of pole/zero and zero/pole. ex: f(s)=s*(s+2)/(s+1). here we can easily sense that there is a occurence of zero(s=0),pole(s=-1),zero(s=-2).
How many flip-flops are needed for an 8-bit counter?
Sixteen. One bit per flip flop. A flip flop can represent only a true or a false. You need sixteen of these (1's and 0's) to make sixteen bits.
How many amps does a 20HP motor draw at 415volt three phase?
Assuming a power factor of approx. 0.8 which depends on motor but this will error on the side of caution IL =S/1.73*VL S=P/pf 20hp= about 15000 W. S=15000/.8 = 18750 VA. IL = 18750/1.73*415 = 26A The motor would draw about 26 A. depending on Load and efficiency
1 btu how many mcf 's?
One thousand cubic feet of gas (Mcf) -> 1.027 million BTU = 1.083 billion J = 301 kWh
BTU in per one square foot of natural gas?
BTU`s are measured in cubic feet
How many tons is a york air conditioner model AC048X1024A?
4 ton 048 in model is btu,s
How many BTU s are in a goodman furnace GMT090-3B?
90,000 BTUs - the 090 is what tells you the BTUs of the unit.
How many btu 's is needed to be removed or added to chill 1000 lbs of water from 75 degrees to 40 degrees?
not sure
How do you find the efficiency of your furnace?
Divide the btu output rating by the btu input rating. Both of these values can be found on the furnace`s nametag.
How many btu equal a 1 ton heat?
Heating units are not measured in tons as AC units are. Heating capacity is referred to in 1000`s of btu output per hour of operation. The ratio of input vs output = the efficiency rating, for example if your home furnace is rated at 100,000 btu per hour input and 80,000 btu per hour output . it is 80% efficient (when it was new). For AC 12.000 btu = 1 ton.
1 pound of -4 degree F ice to 284 degree F steam how many BTUs does it take?
1320 btu`s
What is rheem heat pump model number RPNJ 030JAZ tonage?
2.5 tons. 1 ton =12,000 btu so 30,000 btu=2.5 tons. The 30 in the model # denotes btu of the unit in 1000`s.
How many BTU s is needed to reach 115 degrees f?
That depends on the starting temperature, the substance being heated, and how well insulated it is from its surroundings.
What does 180.0 MBTUH mean?
180 thousand BTU,s or 1.8 Therms.
Would a 8000 btu and a 5000 btu and a 12000 btu cool a 1280 sq foot trailer?
Barely. I think you'd be happier with two 8's and a 12. Of course, it depends on the configuration of the room, the location of the units and the climate, etc.
