They are leak proof and mostly fit in the car cup holder.

Calculator:Air Flow Rate through an Orifice TLV - A

Online calculator to quickly determine Air Flow Rate through an Orifice. Includes 53 different calculations. Equations displayed for easy reference. Correct size for pressure vacuum breaker?I would guess they're just doing a CYA, saying to be reasonable. For example 3/4 vs. 1" could go either way but 'Don't use a 2" vacuum breaker on a 3/4" line or vice versa and expect us to back you up.'. On the capacity graphs, at 7.5 feet/sec:3/4" yields about 12 GPM at Leak rate calculator - LMNO EngThe Bernoulli equation has many applications. Leak rate is one application where it is widely used. Since a pipe is usually much larger diameter than the hole, V 2 >>V 1. Since the elevation change Z 2-Z 1 is typically very small compared to other terms in the Bernoulli equations for a pipe leak application, Z 2-Z 1 =0. Thus:Solve for V 2:

Package Integrity Testing of Pouches

vacuum as well as the change in vacuum over a predetermined test time. The changes in vacuum indicate the presence of leaks and defects within the package. The VeriPac D-Series testers are also capable of testing different size pouches, stick packs and sachets without any changeover in Permeability Testing of Impacted Composite Laminates various applied pressures of helium so a pressure versus flow rate chart could be created. Section 2.4.2 will present equations and experimental results to show how various parameters could affect the flow Professional EVAP Smoke Machine Leak Tester with Port Includes EVAP PORT ADAPTER & a tapered smoke tip to easily hook up to different size hoses. Attached handle makes for easy carrying and hanging of unit. Whip hose ensures unit will not tip over or tilt once you hook up to your air supply hose. All units are electrically tested prior to shipment so these are guaranteed to work when you get it.

Proper PCV Valve Selection for a High Performance

different vacuum lines, but the internal operation was the same as it has been since the early 60s. Stock PCV valves have one airflow path through the valve. An internal pintle is biased by a spring, which controls the flow rate based on vacuum level. Orifice sizes inside the valve dictate the flow under various modes of operation. Research on the untouchable ultrasonic leak evaluation increase of the size of leak at the same detecting distance. The amplitude peak had something to do with the size of the leak and surface condition of the leak. Because these factors have influence on the status in which the gas pass though the leak. Tab. 2 maximum detecting distance for the different leaks Leak VP67 - 6 CFM Vacuum Pump - Fieldpiece InstrumentsFlow Rate:6CFM; Oil Capacity:8oz (237mL) Oil Compatibility:Fieldpiece Vacuum Pump Oil (Highly refined and optimized for proper sealing and lubrication) Fieldpiece part numbers:OIL8X3, OIL32, OIL128; Oil Backlight:Blue LED; Oil Drain:Ball valve; Port Sizes:(1) 1/4, (2) 3/8, (1) 1/2 Compressor:Rotary vane, two stage; Motor:1/2 HP AC; RPM:3440

Service - VACOM

Vacuum Specific Measurements Leak Test for Vacuum We carry out helium leak tests of all common designs and assemblies. We detect and document leak rates to 1 x 10-9 mbar l / s, 1 x 10-10 mbar l / s and 5 x 10-11 mbar l / s. The lower the leak rate the higher the effort. A leak test printout is part of the service agreement.
