A checked, locked Excel workbook for building services engineers. Three calculations that come up on almost every job, set out as clean A4 calc records you can file:
Pipe sizing and pump duty: up to 25 sections, load and delta-T or direct flow, copper and steel pipe tables, velocity and Pa/m checks, index run, component losses and pump duty in kPa and metres head.
Expansion vessel sizing: sealed heating and chilled water, EN 12828 method, picks the next standard vessel and gives the cold fill pressure.
Hot water storage: peak demand, recovery from boiler or heat pump, usable volume, standard cylinder selection and reheat time.
Methods are stated on the cover, formulas are locked, inputs are clearly marked and pipe and equipment data is editable to suit your suppliers. Built by a practising M&E consultant. Single-practice licence. Delivered as an .xlsx download.
