Gradually varied flow occurs when the change in flow depth per change in flow distance is very small. In this case, hydrostatic relationships developed for uniform flow still apply. Examples of this include the backwater behind an in-stream structure (e.g. dam, sluice gate, weir, etc.), when there is a constriction in the channel, and when ...
Process flowsheeting is the use of computer aids to perform steady-state heat and mass balancing, sizing and costing calculations for a chemical process. It is an essential and core component of process design. The process design effort may be split into three basic steps Synthesis; Analysis and; Optimization.
Figure 1a shows the flow through the nozzle when it is completely subsonic (i.e. the nozzle is not choked). The flow in the chamber accelerates as it converges toward the throat, where it reaches its maximum (subsonic) speed at the throat. The flow then decelerates through the diverging section and exhausts into the ambient as a subsonic jet.
In order to calculate the Level of Service for the ICU method, the ICU for an intersection must be computed first. [3] ICU can be computed by: ICU = sum(max (tMin, v/si) * CL + tLi) / CL = Intersection Capacity Utilization CL = Reference Cycle Length tLi = Lost time for critical movement v/si = volume to saturation flow rate, critical movement
graph with an example of steps in a failure mode and effects analysis. Failure mode and effects analysis (FMEA; often written with "failure modes" in plural) is the process of reviewing as many components, assemblies, and subsystems as possible to identify potential failure modes in a system and their causes and effects.
The project has two critical paths: activities B and C, or A, D, and F – giving a minimum project time of 7 months with fast tracking. Activity E is sub-critical, and has a float of 1 month. The critical path method (CPM), or critical path analysis (CPA), is an algorithm for scheduling a set of project activities. [1]

Failure mode effects and criticality analysis (FMECA) is an extension of failure mode and effects analysis (FMEA).. FMEA is a bottom-up, inductive analytical method which may be performed at either the functional or piece-part level.
