How hydraulic modeling can improve the efficiency of your pump systems In spite of their large operating cost, most pump systems are inefficient by design. Among the common design problems are non-optimal pipe sizing, control valve utilization and, perhaps most common, incorrectly sized pumps. How a pump operates depends on the system, so improvements must focus on the system as a whole. |

The traditional approach to experimentation, often referred to as the scientific method, requires changing only one factor at a time (OFAT), but this method only allows one to see things one dimension at a time. By varying factors only at two levels each, but simultaneously rather than one at a time, experimenters can uncover important interactions. |

Designing equipment for solids is not an exact science. The flows of gases and liquids are generally better understood than those of solids. Most production problems arise from flaws in the design. This article presents questions you can ask yourself to ensure reliable flow in your silo. |

Better Design Is No Pipe Dream The benefits of using pipeline simulation tools at the piping and instrumentation diagram (P&ID) level, rather than running simulations just on the process flow diagram, can often be overlooked. |

Reviewing the use of fouling factors in heat exchanger design HTRI plans to review and analyze specific exchanger services to develop design margins for use in sizing heat exchangersrather than relying on fouling factors. |

Your job is still safe... for now With mechanical simulation tools, one engineer can do the work of an entire staff. With chemical processes, however, simulation tools aid the staff but dont replace it yet. |
