### ðŸ‘‰ How do you calculate btu for natural gas?

To find out the BTU's per pound, **divide your therm into 100,000 BTU's** (100 cubic feet or 1 standard therm). To find the number of BTU's per GGE, multiply the result by 5.66 (1 standard GGE). For example, if the therm of your area is 4.96 lbs, divide that number into 100,000 and you have the resulting BTU's per lb.

Fuel suppliers will usually quote the HHV and it will be this measure that will be used when kWh unit charges are applied for the fuel. In the case of natural gas the ratio of HHV to LHV is approximately 1.108:1. Hence, when performing a cost benefit analysis for a CHP application, it is the HHV figure which should be used.

If the initial and final temperatures of the water is measured, the energy released can be calculated using the equation H = Î”T mCp where H = heat energy absorbed (in J), Î”T = change in temperature (in Â°C), m = mass of water (in g), and C p = specific heat capacity (4.18 J/gÂ°C for water).

The final remaining conversion is to adjust the heat rate at ISO conditions using LHV to the heat rate at ISO conditions using HHV of the fuel. This is performed using a multiplier provided by the manufacturer. This conversion is performed by multiplying the Heat Rate at ISO Conditions btu/kWh LHV by 1.1081. This factor was received in an email dated May 29, 2018 from Jason Richardson, Performance & Testing Engineer for MHPSA. This conversion yields the following calculation:

To calculate the cost using a UK gas price we would want to have assumed an efficiency of 80 % HHV. This is because UK gas prices are given on an HHV basis. Either convention can be used as long as all of our fuel consumptions, efficiencies and energy prices are given on the same basis. Consistency is crucial. Most data sheets will specify gas consumption or efficiency on an LHV basis. If you are working in a country that prices fuel on an HHV basis (such as the UK) you will need convert ...

To calculate energy consumption costs, simply **multiply the unit's wattage by the number of hours you use it to find the number of watt-hours consumed each day**. For example, let's say you use a 125 watt television for three hours per day.

- Calculate The Total Energy bill of the consumer if per unit rate is 9 (In $, Â£, â‚¬, INR ,Rs, DHR, Riyal etc) [Take 1 month = 30 Days]. Solution:
**1unit = 1kWh**. So Total kWh = 1000 Watts x 24 Hrs x 30 Days = 720000 watts/hour. we Want to convert it into Units, Where is 1unit = 1kWh.

- Calculation of the energy consumption.
**E (kWh/day) = P (W) x t (h/day) / 1000 (W/kW).**It means that the energy in Kilowatts hours in a day is calculated by multiplying the power in Watts (W) by the number of times (hours) used in a day then divided by one thousand watts per kWh.
