Physics

Adjust an OTDR event location for a launch cable, preserve event loss in dB, and compare it with your project limit.

Estimate pneumatic cylinder free-air demand in SCFM, peak simultaneous flow, average air use, and compressor planning capacity.

Estimate ceiling speaker count, grid spacing, rows, columns, and wall offsets from room size, mounting height, and coverage angle.

Calculate projector pixels per degree, image pixel density, viewing angle, and compare 1080p, UHD 4K, and DCI 4K at your seat.

Calculate required compressor airflow and check a compressor using tool air use, running time limits, and matching PSI ratings.

Calculate cascaded RF gain, noise figure, input IP3, and output IP3 from ordered active and passive stages.

Calculate LMTD, corrected driving force, terminal temperature differences, and required heat-exchanger UA from load and temperatures.

Check CCTV pixel density, identification detail at a target distance, and estimated maximum identification distance in feet or meters.

Estimate line array vertical coverage, endpoint aim angles, average joint splay, coverage room or shortfall, and listener throws.

Calculate microphone preamp gain and check available gain, analog clip margin, and digital peak margin from your audio gear specs.
