Calculate one-way fiber propagation delay, fiber-only RTT, and optional equipment-added latency from route or map distance.

Estimate cooling tower evaporation, drift, blowdown, makeup water, and scheduled gallons using target or measured cycles.

Estimate annual steam loss and avoidable energy cost from a measured steam leak or failed-open trap details.

Estimate centrifugal pump flow, total head, and shaft power after a speed change or impeller trim.

Calculate estimated parabolic dish gain, 3 dB beamwidth, and wavelength at one frequency or across a frequency range.

Calculate rectangular waveguide mode cutoff, propagation at a chosen GHz frequency, and the dominant-only operating range.
