1. Minimizing Pumping Costs
   In this example we will see how selecting the proper design point can improve a pump's operation and minimize pumping cost. Before a pump is selected for a given application, a series of calculations must be performed to determine the system's static head and pipeline head loss for a given desi ...
2. Balancing a System
   Piping systems providing heat transfer fluid to a variety of loads can present their own special problems. Since there are multiple paths for the fluid to travel, the system naturally balances so the pressure drop around each loop is equal. It is highly unlikely that when all of the valves are ...
3. Correcting Problem Control Valves
   Piping systems are a collection of pumps, control valves, components, tanks and vessels. Often even the simplest piping system can present a large problem when it is not operating properly. In this example, we have a single pump circuit that pumps from a storage tank to a pressurized tank. A he ...
4. Using Overtime In Ship Deballasting Operation
   Background A naval architect and PIPE-FLO® user recently called for technical support on a unique piping system problem he was trying to solve. He was working with a shipyard and was tasked with determining a method to pump out six ballast tanks on a ship while the ship's cargo was being loa ...
5. Time Simulation with PIPE-FLO
   It is often necessary to see how a piping system operates over time. For example, as a tank is pumped down, the static head increases resulting in a smaller flow rate through the pump. This reduction in flow rate causes the tank to take longer to pump down. This type of calculation is called an ...
6. Case Studies Overview
   There are a variety of case studies on the Engineered Software Website, with more being added. These case studies were created for some of the most typical applications PIPE-FLO is called on to analyze. Pump Sizing - Selecting the proper pump is the most important step in the designing of a ...
7. Pump Sizing
   Selecting the proper pump is the most important step in the development of a piping system. The pump must be sized to handle the desired flow rate at the required pressure from the supply to the destination. In order to size a pump, you must take into account the change in elevation and pressur ...
8. Finding System Bottlenecks
   System Bottlenecks This case study is based on an actual analysis of a reclaim water pump system in a nickel mining operation. The reclaim water system consisted of four 10-stage vertical turbine pumps operating in parallel, and a 25,000-foot long 20-in diameter pipeline passing 12,700 gpm of r ...
9. Time Simulation with Overtime
   It is often necessary to see how a piping system operates over time. For example, as a tank is pumped down, the static head increases, resulting in a smaller flow rate through the pump. This reduction in flow rate causes the tank to take longer to pump down. This type of calculation is called an ...
10. Variable Speed Pumps
    When designing piping systems in which the system demand varies (for example, a chilled water distribution system with varying loads throughout the year), variable speed pumps may be an effective energy and cost savings option. In these systems, the pump speed can be adjusted to meet the varying ...
11. System Expansion
    Piping systems are in a continuous state of change. Over time new loads are added to cooling systems, new demands are placed on a distribution system, and plant operation systems are expanded or changed. No matter how the system is modified, any change to the system affects the pressure and flo ...
