even if the cfm is set at 1050, the duct system may not be designed to deliver that amount of air flow. a two ton system should be putting out about 800 cfm. maximum. 11-29-2012, 11:08 pm 3
often it is necessary to convert a measure of capacity from one term to another. the conversion table will allow you to quickly convert various measures of capacity. the table and formulas can help you size and pick out components such as condensate pumps and boiler feed pumps. some additional conversion factors that may prove helpful are shown below.
start studying hvac final. learn vocabulary, terms, and more with flashcards, games, and other study tools. search. it requires 1 hp to produce 1-1/3 tons of cooling. b it requires 1 hp to produce 1 ton of cooling. what type of units are required by the epa to have service valves?
divide the total btu requirements for the room by 30 to obtain the necessary cfm requirements. you need 1 cfm for every 30 btu in a room.

refrigeration or cooling capacity can be measured in tons. a water-chiller refrigeration ton is defined as: a ton is the amount of heat removed by an air conditioning system that would melt 1 ton 2000 lbs. of ice in 24 hours. the heat required to melt 1 lb of ice at 32 of to water is 144 btu.
how can we calculate the required torque to move a massive object by means of gear assembly? i need to know the power of a motor in hp required to move a vehicle of about 150 kg.
this means the total weight at lift-off is 2 million x 9.8, which is approximately 20 million newtons 20 mega newtons . the thrust of each of the big white solid rocket boosters on the side was 12.5 million newtons, and the three main engines at the tail end of the bit that looks like a plane the space shuttle orbiter had a combined thrust of 5.5 million newtons.
re: calculating amount of steam required 25362 chemical 20 apr 10 23:59 assuming steam is saturated in both cases, and if steam and water are mixed, and the mix reaches a final temperature of 160 o f, the heat supplied by steam should be increased by the sensible heat from its saturation condensation temperature down to 160 o f.
step 1: determine properties of steam produced using the steam property calculator, properties are determined using steam pressure and the selected second parameter temperature, specific enthalpy, specific entropy, or quality . the specific enthalpy is then multiplied by the mass flow to get the energy flow: pressure = 54.3 psig; temperature = 395.1 c
the ammoniation of 30 000 tonne of st requires 900 tonne of anhydrous ammonia, which can be transported by a 3-ton truck tank once daily table 6-7 . at the same time, 30 small bottles with 200 kg and other facilities, such as a farm vehicle, a small four-wheel tractor and trailer, are also needed.
thus, 1 tonne of refrigeration is 10% larger than 1 ton of refrigeration. another unit of measure is the calorie which is the amount of heat removal required to raise or lower the temperature of one gram of water by one c. a kilo-calorie is the amount of heat required to raise or lower 1 kg of water by 1 c.
how to calculate pressure from tonne scale to mpa in a manual hydraulic press? press fit - todetermine the force required to press fit two most of the servo valves taken up for research
the steam required for steam tracing is calculated on the basis of the amount of heat transfer that is required or the temperature that you want to maintain with the help of steam.
the process has a capital cost of $29.4 million over the two years of construction, with a fixed capital investment of $25 million, and a working capital of $4.4 million. the process has a discounted payback period of 4 years after startup. the process has a net present value of $27.8 million at a minimum rate of return of 15%.
if using pool chlorine 12% sodium hypochlorite use half the amounts below. if a thorough disinfection is needed and time is short, use a 50 ppm or 100 ppm residual and let sit for 2 to 6 hours. drain and flush tank if using these higher levels of chlorine.
there are two main types of containment systems: self-supporting tank and membrane tanks. current lng vessels have 135 thousand m3 carrying capacity approximately 60 thousand metric tons and cost approximately u.s. $160 million. these carriers either consume boiloff gas or reliquefy the gas and use diesel as fuel.
a piercing valve is a valve with a pointed sharp tip that is used to gain access to a sealed refrigeration system that does not have service valves or schroeder ports. and is to be used as a
how can we calculate the required torque to rotate 1200 kg of mass? i would like to calculate torque to rotate 1200 kg of mass which is attached in 1.5' dia shaft. shaft is supported by 2 bearings
