The BTU (British Thermal Unit) is a standard measure used for rating the energy output of appliances (such as heating and cooling systems) and for measuring energy consumption. One BTU is equal to the energy needed to increase the temperature of one pound of water by one degree Fahrenheit. ...
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...
Calculating the energy in joules required to heat a 256 grames of water at -107 degrees to 333 degrees C. Provide two uses of copper. Explain the specific heat capacity of the metal and link its use to specific heat capacity. How does it having a small specific heat capacity make it use...
Plus they are our client so I'm supposed to be smart engineer with the equations. Regarding the heat required to evaporate the water, allow me to ask a dumb question. Isn't the heat output from AHU energy measured in BTUs? So the air flow rate, whether stagnant or 10,000 CFM isn...
Example of a question LearnMetrics’s received:We have a 300 square foot standard bedroom. How much CFM should a fan for such a room have if we’re looking to completely change all air 2 times per hour (every 30 minutes)? CFM Calculation:Airflow has to be strong enough to change the...
Here's a general calculation you can start with to get a baselineBritish thermal unit(Btu) cooling size: (Room square footage x 20) + (IT equipment watt usage x 3.14) + (Active people in the room x 400) But this is just a starting point. If you want a more accurate estimate and ...
A drink bottle has a capacity of 290 mL. What is this volume expressed in SI units of m^3?(Give your answer to at least two significant figures) What are the units of molar heat capacity? Determine the volume of oxygen gas required to completely combust 5.5 mol of propane (C_3H_8)...
When calculating the amount of cooling (air conditioning) required in a room, you should take into account that the room should always be maintained at an ambient temperature of much less than 35 degree Celsius and that any other equipment in the room will also generate heat. Officially, Int...
capacity. A better unit for measuring cooling capacity is the British Thermal Unit (BTU), where 1 BTU is the energy required to heat one pound of water by 1 degree Fahrenheit. The BTU is the standard by which air conditioners are measured in North America, as well as in many other ...
to boiling water Sensible and Latent Heat:Whenever a specific liquid (water) gets a particular amount of heat, then there would be sensible and latent heating takes place. The value of the sensible and latent heat decides the value of...
