The majority of practical problems fall within the turbulent flow range and this calculator determines the required pipe size, flow or pressure loss for any liquid, e.g. water, fuel oils, acids, solvents, and also for any gas (at low pressures) flowing under turbulent conditions in steel or cast iron pipes. PRESSURE LOSS, FLOW or PIPE SIZE are found from the front of the calculator by a simple ...

PIPES, DUCTS OR CIRCULAR SECTON One side of the calculator solves the rational formula for water flow in pipes and ducts of circular section. The answers have been checked against a large number of well authenticated practical tests on actual pipelines from small metal tubes to long concrete tunnels up to 6 metres dia. and give accuracy appreciably better than the usual Hazen Williams formula. F...

A single-sided calculator to rapidly determine the voltage drop in cables and to give the required cable size to meet specified maximum losses. The length of circuit is simply set to the current and the cable size read opposite the allowable voltage drop. A separate section finds the current for either single or three phase from the kW required and the supply voltage. MODEL Metric SIZE 5...

This is a handy pocket-sized instrument designed for converting dimensions measured in feet, inches and fractions of an inch instantaneously to millimetres, and vice-versa. The scaling gives a high degree of accuracy and is varied to suit practical requirements, being more open at the lower end so that small dimensions are easily read to 1/64" whilst larger ones near 100 ft. are read to 1/4". Thu...
