• 3 Phase Electrical Current

For 3 PHASE circuit calculations of the electrical CURRENT in AMPERES by phase, for a specificated POWER in KVA and VOLTAGE in VOLTS between phases.

• 3 Phase Motor

Calculates 3-phase amperage if you know the Power and the AC Voltage. Enter either Horsepower or Kilowatts in the "Power" section. Enter either Voltage Line-to-Line or Line-to-Ground in the "AC Volta ...

• Affinity Laws

Calculates a pump's flow, head and power based on the laws of Affinity given a future speed from initial speed, flow, head and power. Speed is shaft speed.

• Air Changes

Air Changes per Hour using the dimensions of the space. Air volume rate is in cubic feet per minute.

• Air Core Inductor

Computes the inductance of an air core inductor with the given size and number of turns.

• Ankers ROSR en RL 2006/87/EG B2

Bron ROSR en richtlijn 2006/87/EG, bijlage II

• Atmel Timer 16- and 8-bit

Atmel 8 and 16 bit timers

• Attenuators and DB

Computes resistor values for pi and T attenuators, and converts voltage/current ratios and or power ratios to and from DB.

• Belts

Computes the length of a v-belt or flat belt which will fit the given pulley diameters and center distance. Span, the distance between the tangent points where the pulleys contact the belt, is useful ...

• Block Speed

Calculates the travelling block speed such as you would find on an oil drilling rig.

• Cantilever Beam

Computes the equation for a cantilever beam with a load at the end.

• Capacitor Charging

v= voltage across the capacitor

• Capacitor Discharging

v= voltage across the capacitor

• Capacitor I V

Capacitor Voltage Current Relationship

• Carbon Equivalent

Calculates Carbon Equivalent. The lower the value, the better the weldability. Values greater than 0.45 are generally considered too brittle, with poor weldability.

Calcula la corriente por fase a partir de los KVA y el Voltaje, en circuitos monofasicos y trifasicos.

Calculation of the polytropic head of a centrifugal compressor. Uses ideal gas relations to calculate polytropic exponent.
