Generation Capacity Factor
Compare actual energy with continuous output at an entered constant capacity over the same period.
Use generation capacity factor →Energy Unit Conversion
Convert an energy quantity between kWh, joules, megajoules, International Table Btu and a declared therm convention. Keep energy separate from power.
Use energy unit conversion →Petroleum Barrel Volume
Convert petroleum barrels, U.S. liquid gallons, liters and cubic meters. The barrel is explicitly 42 U.S. liquid gallons, with no temperature correction.
Use petroleum barrel volume →Liquid Mass & Volume
Estimate liquid mass from volume, or volume from mass, using your entered density. See liters, cubic meters, kilograms, tonnes and pounds together.
Use liquid mass & volume →Fuel Cost per Input Energy
Turn your fuel unit price and heat content into input-energy cost, including a separate delivered-purchase perspective.
Use fuel cost per input energy →Motor Efficiency Savings
Convert the same mechanical shaft output through two entered efficiencies, then compare annual energy charges and simple payback.
Use motor efficiency savings →Pipe Flow Velocity
Calculate pipe velocity from flow rate and actual internal diameter. Enter L/s, L/min, m³/h or U.S. gpm with mm or inches, and see mean velocity in m/s and ft/s.
Use pipe flow velocity →Compressed Air Leak Cost
Calculate the electricity cost of a measured compressed air leak in CFM or m³/min, using pressurized hours and matched compressor energy data.
Use compressed air leak cost →Compressed Air Unit Cost
Calculate electricity-only cost per m³ and measured kWh per m³ from total compressor electricity and total delivered air volume for the same period.
Use compressed air unit cost →Fuel Blend Energy Scenario
Sum two component heat contents on one matching mass or feed-volume basis and report a weighted input value.
Use fuel blend energy scenario →Fuel Volume to Energy
Convert a liquid volume to litres, then apply your supplied fuel heat content on its stated gross or net basis.
Use fuel volume to energy →Natural Gas Volume to Energy
Apply a supplied gas billing-volume factor and heating value, with explicit energy-unit conventions.
Use natural gas volume to energy →Oil & Gas Production Value Scenario
Multiply oil and gas quantities by matching prices for one period and subtract only the deductions you enter.
Use oil & gas production value scenario →Tank Fill & Drain Time
Calculate ideal inventory-change time from simultaneous constant inflow and outflow.
Use tank fill & drain time →Viscosity Unit Converter
Relate dynamic and kinematic viscosity using density supplied for the same fluid state.
Use viscosity unit converter →Heat Exchanger Thermal Duty
Signed heat removed in kW = mass flow in kg/s × enthalpy drop in kJ/kg.
Use heat exchanger thermal duty →Heat Exchanger LMTD
Counterflow terminal approaches are hot-in minus cold-out and hot-out minus cold-in.
Use heat exchanger lmtd →Heat Exchanger UA Scenario
Effective UA in kW/K = entered thermal duty in kW ÷ (applicable correction factor × reviewed LMTD in K).
Use heat exchanger ua scenario →Ideal Gas Volume Scenario
The ideal-gas equation is pV = nRT.
Use ideal gas volume scenario →Pipe Pressure-Drop Scenario
Convert diameter to metres and flow to m³/s.
Use pipe pressure-drop scenario →Pump Hydraulic Power
Hydraulic kW = fluid density × standard gravity 9.80665 m/s² × flow in m³/s × differential head in metres ÷ 1,000.
Use pump hydraulic power →Refinery Stated-Basis Yield Scenario
Main-product yield is main output divided by the explicitly entered qualifying input, multiplied by 100.
Use refinery stated-basis yield scenario →Reynolds Number
Dynamic-property mode uses Re = density × velocity × characteristic length ÷ dynamic viscosity.
Use reynolds number →Before you use these calculations
Check pressure is absolute where required and keep temperature in the stated scale.
Use composition-specific properties or supplied compressibility factors.
Converted volumes and energy are not custody-transfer certification or process operating limits.
Start with the example, replace the assumptions with your measurements, then change one input to see its effect. Save or export the scenario if you need to keep its basis.
