The input power, that is, the power required to operate the pump should be stated in Hp (horsepower) on the pump’s nameplate. It can also be calculated by the 3-phase power equation:
P(in Hp) = VI(1.7c) = Rated Voltage x Rated Current x 1.73/ %Efficiency
If this is a consumer grade pump that operates on 120Vac, then the equation becomes P = VI, simply multiply the operating voltage, 120 x current (which is the number followed by the letter “A”.
The output power, which really is not technically power, but rated in Gpm (gallons per minute), or capacity should also be on the nameplate. If you have the make, model, and (not necessarily needed) the serial number (also on the nameplate) you could call the manufacturer’s customer service dept. As an application engineer, I have contacted countless manufacturers, and service dept’s for assistance. It is now big deal to them, they will be happy to answer your questions.

Purpose of the gap in the road is to allow the road to exPAnd and contract with temperature changes without causing damage or deformation to the road.

When a dam is to be built, a diversion tunnel is usually bored through solid rock next to the dam site to byPAss the dam construction site. The dam is built while the river flows through the diversion tunnel.

While he did not build the structure (he died in l959), there is some evidence the idea was suggested under a different name (Illinois Building) by Frank Lloyd Wright, one of the few true skyscrapers in which he had a role. The original design for the Illinois Building would have topped off at 5,280 Feet! The Swears tower is a quarter of this at most, but there are similarities.

Tensile Strength, Ultimate 7.00 – 20.0 MPA 1020 – 2900 PSI
this is the strength in a pure tension test. For bending use:
Modulus of Rupture 0.00410 – 0.0276 GPA 0.595 – 4.00 ksi

If you have never used a ice dam melting sock on your roof before, you will find that they provide an inexpensive method for removing roof ice dams and improving your home’s heating efficiency. Roof ice dams are an annoying source of roof damage, leaks, and heat loss in the winter. The main causes are drip melt from improperly capped warm air vent pipes and poor roof insulation. Laying a ice melt sock onto the roof so it crosses the ice dam and overhangs the gutter, will melt through the snow and ice and create a channel for water to flow down into the gutters or off the roof. If done properly those ice sickles that form as the snow melts from the edges of the gutters will never appear, they too are a cause of much damage and are dangerous to life and limb.
