LPG contains propane and butane LNG contains methane
The Specific heat of Naphtha is 0.526 BTU/Lb F
Depends on the company you work for. I sailed as a third engineer just 2 years ago and I earned US $65,000 per year.
how much does it cost to build a big water plant?
Because LPG is a mixture, the value of the latent heat will depend on the exact composition of the mixture. The main components of LPG are:propane - C3H8propylene (propene) - C3H6isobutane - C4H10n-butane - C4H10butylene (butene) - C4H8Since LPG is usually mostly propane and butane, a rough estimate would be in the range of the values for these two components. Note that latent heat is dependent on temperature as well. for the purposes of this answer we will use 30 °F (near the boiling point of butane at atmospheric pressure)Hvap(propane @ 30 °F) = 163 BTU/lbHvap(butane @ 30 °F) = 166 BTU/lb
Generally, one gallon of LNG (liquefied natural gas) contains around 135,000 British Thermal Units (BTUs) of energy. This high energy content makes LNG an efficient fuel source for various applications in transportation and industry.
1 kg of Lng of that particular quality will have say ' X ' k.cal per kg of calorific value from the data of LNG producer. Then 1 Ton of LNG will have 1000X when converted to B.T.U it will be 3967 multiplied by 1000 X What "particular quality" is referred to above??? Generally speaking 1 tonne (1000Kg) of LNG is considered to have a caloric value of 48 MMBtu
1ton LNG is equivalent to 2.193 cubic meters = 1315.79 cubic meters of degassified natural gas.In thermal unit, it is equivalent to 50mmBtu.However it depend on the composition and caloific value of Naural gas considered.The above value can be used for estimation purposes.
The cost to buy LNG in Australia is approximately $A 14mmbtu based upon the recent export price of published export contract outcomes
This depends on the cost per kilowatt hour in your area.
The cost of one BTU (British Thermal Unit) can vary depending on factors such as location, fuel type, and market conditions. As of 2021, the average cost of one BTU of natural gas is around $0.00001, while the cost of one BTU of electricity is around $0.00003. It is important to check current prices to get an accurate value.
The BTU content of liquid natural gas (LNG) varies depending on its composition, but on average, it is around 21,500 BTUs per cubic foot.
OK
The total cost of buying a 9000 BTU ductless air conditioner ranges from $620 to $700. The cost of installation depends on the dealer or contractor you hire.
1030-1060 BTU/cf 1 gal (US) = 0.133 cf (cubic foot) 1 cf = 7.48 gal converting units, 138 - 142 BTU/gal X 600 ( the approximate volume change from liquid to gas = 84,000 BTU/galhttp://www.retailenergy.com/hybrid/Liquified%20Natural%20Gas.htm The previous answer neglected to account for the difference in the BTU/vol of methane as a liquid vs the BTU/vol of methane as a gas
The cost to heat a pool can vary depending on factors like energy costs and usage patterns. However, you can estimate the cost by calculating the BTU input per hour of the heater (399,000 BTU) and factoring in the energy cost per BTU in Pennsylvania. You can then multiply the cost per BTU by the number of hours required to heat the pool to 80 degrees Fahrenheit to estimate the total cost.
It depends on the cost of electricity and the cost of natural gas in your area. Generally, using a 5000 BTU natural gas heater is cheaper than using a 1500 watt electric heater. Natural gas is typically more cost-effective for heating compared to electricity.
