A water distribution system containing approximately 700 pipes in this example. There is no limit on number of pipes or nodes.

What is minimum loop pipe size to deliver even sprinkler water flows?
 

The fired heater is hydraulically limited. Will increasing the tube pass from 2 to 4 in the convection section solve the problem?
 

What are the required pump size and the NPSH to send flow from a column (source) to a fractionator (sink)?
 

De-ionized water flows from tank to points of use while a portion of it re-circulates to avoid stagnation. What is the optimal header line size to meet target DI water supply requirement?
 
 

Simultaneous reliefs from two separate locations in one service. Multiple relief valves feeding to a common relief header from each relief location. Two relief headers feed to a knock-out drum. Relief vapors go to a flare. Do existing sizes of relief valves satisfy the new relief load?
