I have an open drum filled with water, 100lt and heating with a LP gas burner. How do I calculate the BTU hr heating the water to say 100 C I need a safety tilting valve to cut off the gas flow...
What amount of heat should be applied to a 12 kg silver bar to raise its temperature from 22 degrees C to 90 degrees C if the specific heat of the silver is 235Calculate the amount of heat in Joules needed to transfer 1.0 L of...
What is BTU is an AC unit? Simply put, it’s the capacity or power of the AC. The bigger the BTU, the more cooling effect an AC unit can provide. Here is an example of how you can calculate how many BTUs you need to cool down a 500 sq. ft. area with 8 feet ceilings, avera...
Calculate the mass flow rate of fuel (natural gas, CH4) required to heat the water flow to the conditions of the problem if the electrical heating device is replaced with a gas-fired boiler. The high heating value (HHV) of the fuel is 50.02 MJ/kg Calculate the mass flow ra...
Running Wattage (5-Ton 18 SEER)= 60,000 BTU (This is equal to 5 tons) / 16 SEER =3,750 Watts Now that we have the running wattage, we can calculate the kWh usage. This unit – with 3,750 running watts – will use: 3.75 kWh per hour. ...
uses the Rankine Cycle. None of these cycles can be used to completely convert energy into work. This is because all of them have to reject heat into the environment. A power plant or steam engine has to condense steam in order to send the water back to the boiler (losing energy). An...
Calculate the energy needed to bring a cup of water (about 250 g) from 10 C to the boiling point. Then find the time it takes to heat this water A kettle draws power of 2000 W and has an efficiency of 85%. You fill the ...
Efficiency is defined as the ratio of useful energy to the input energy. This is important because there are some losses when energy is being converted from one form to another. The general equation for the efficiency is shown below.
Calculate how much energy is required to heat 1.295 g of ice at 200.0 K to water at 356.00 K. A natural gas water heater has an AFUE of 80% over 1 month, 10,000 gallon from 160 F to 130 F. Natural heat has a...
Answer to: How much natural gas is required at a power plant with a heat rate of 5,000 BTU/kWh to run a 5 kW air conditioner unit continuously for...
