The peak expiratory flow (PEF), also called peak expiratory flow rate (PEFR), is a person's maximum speed of expiration, as measured with a peak flow meter, a small, hand-held device used to monitor a person's ability to breathe out air. It measures the airflow through the bronchi and thus the degree of obstruction in the airways. Peak A peak stress is a highly localized stress that exists at a discontinuity in the load path. An example of a peak stress is the high localized stress at the root of a thread in a bolt. Source: API SPEC 16R, Specification for Marine Drilling Riser Couplings, Exploration and

Motor Vibration Analysis: Keeping it Simple

There's typically no way around it. At some time during a motor's life, it is likely to experience high vibration levels. Again in 2016, conveying technical content through visual images in the form of photo galleries proved to be one of the largest website traffic

2016/9/1That's the confusing part, and that's what I wrote about in this blog titled, "When is Normal not so Normal". When using the "Auto" trigger mode, if the scope doesn't receive a valid trigger within a certain amount of time (varies depending on the timebase setting),

Editor's Note: This is the first in a six-part series on centrifugal pump efficiency. For other articles in this series, click Centrifugal Pump Efficiency series. In this multi-part series, we will investigate several aspects of centrifugal pump efficiency.First, I will define

Capacitor Characteristics and Capacitor Specifications

DC and AC voltage values are usually not the same for a capacitor as the AC voltage value refers to the r.m.s. value and NOT the maximum or peak value which is 1.414 times greater. Also, the specified DC working voltage is valid within a certain temperature range, normally -30C to +70C.

12d Model – Drainage Analysis Module – Hydraulics Page 4 of 11 Definitions: cont dn = Normal Depth The depth in the pipe when the slope of the water surface of the pipe flow, Q, is parallel to the pipe slope. If Q is greater than Qcap, dn is set to the obvert of the pipe. is set to the obvert of the pipe.

Note that for all functions, leaving out the mean and standard deviation would result in default values of mean=0 and sd=1, a standard normal distribution. Another important note for the pnorn() function is the ability to get the right hand probability using the lower.tail=FALSE option.

To determine peak demand, read down the column in Table 1 under the number of bathrooms to the normal seven-minute peak demand total. Note this figure, which in a two- bathroom house is 98 gallons. Then read down the same column to the minimum -sized

The gambrel design, like gable, has vaulted ceilings and even more upper air space than gable. Lofts are very common in this design for homes. For a simple (non-crossing, non-dormer) gambrel frame, cost for labor and materials will run $28,000 to $50,000.

For design purposes, the most important aspect of choosing the appropriate nut is to select a nut with a proof stress equal to or greater than the ultimate tensile strength of the bolt. Caution : It appears that one could theoretically increase the thread strength by increasing the length of engagement.

Chapter 8: Stormwater Management Design Examples This chapter presents design examples for two hypothetical development sites in the State of New York. The first site, "Stone Hill Estates," is a residential development near Ithaca. The second is a

• The peak stress is the strength of the rock. – It may fail catastrophically if the load frame is "soft". Example below is for a "stiff" frame. • The compressive strength of rock is a function of the confining pressure. • As the confining pressure increases so does the

2009/11/2I would just like to get some clarification on calculating peak flows in a residential township. the average annual daily demand is 1200l/d now if the instantaneous peak factor of 5 is used, does this mean that the flow rate at peak demand will be: 1200x5/(24x60x60)=0
