The flow in manifolds is extensively encountered in many industrial processes when it is necessary to distribute a large fluid stream into several parallel streams, or to collect them into one discharge stream, such as in fuel cells, heat exchangers, radial flow reactors, hydronics, fire protection, and irrigation. Manifolds can usually be ...
In fluid dynamics, total dynamic head (TDH) is the work to be done by a pump, per unit weight, per unit volume of fluid.TDH is the total amount of system pressure, measured in feet, where water can flow through a system before gravity takes over, and is essential for pump specification.
The company was the first pump manufacturer to adapt a rotary pump to the dewatering industry. [2] It manufactures all of its pumps in-house and manages sales, rentals and service through domestic and international field offices, as well as a network of third party distributors. George Jr. died in 1979 at age 25, and George Sr. retired in 1999.
Before the purchase, Excel had to resell long-distance service through other companies' networks, such as Frontier Communications. In November 1998, Excel merged with Teleglobe. Kenny Troutt retired as CEO on September 20, 1999, and was replaced by Christina Gold. Excel–Teleglobe was taken over by Teleglobe's major shareholder, Bell Canada ...
Specific Pump Power (SPP) is a metric in fluid dynamics that quantifies the energy-efficiency of pump systems. It is a measure of the electric power that is needed to operate a pump (or collection of pumps), relative to the volume flow rate. It is not constant for a given pump, but changes with both flow rate and pump pressure.
In the latter case, less water supply pressure is required as the hydraulic pressure drop is lower in the branch pipe as water flows from both ends of the branch line to any sprinkler. Grid systems utilizes two large mains at opposite ends of several branch lines which are connected to the mains at each end.
Speck cases were chosen as iLounge's iPhone Case of the Year in 2009 (CandyShell for iPhone 3GS and iPhone 3G), [15] 2010 (PixelSkin HD for iPhone 4), [16] 2011 (CandyShell Flip for iPhone 4S and iPhone 4) [17] and 2012 (CandyShell Flip for iPhone 5).

Cutaway side-view diagram of an axial piston pump 3-D rendering of an axial piston pump with the parts labeled Animation of an axial piston pump in operation. An axial piston pump has a number of pistons (usually an odd number) arranged in a circular array within a housing which is commonly referred to as a cylinder block, rotor or barrel.
