    Dimensions not showing in Part

    Sketch dimensions in V15, I place in Part, do not show up unless I move the cursor over them. The lines and arrow heads show in black, with a gap where the number should be. I.e. |<--- Blank --->| Have I switched something off inadvertently? Tony

    Vacuum Pump Filter Material

    I have purchased 2nd hand a Vacuum Pump, which I intend to use on a Vacuum Table for machining rubber. The inlet (the sucking pipe) is about 1" dia. and has only a corse mesh filter. I intend to make a better filter for swarf and rubber particles, but am unsure as to what material to use for...

    Turning off computer or exiting from program through VB5

    I have a computer running Win98 monitoring a testing machine. The readings are via the parallel port using a Pico adaptor and VB5. The 3.3v from the parallel port via a transistor and 2 relays (one is latching), switch the machine motor. The idea is, that on completion of the test or if the...

The apparatus is inside a laboratory building...

    Side Channel Air Blowers

    I have an application requiring 120 l/m (4.25 ft3/min) of air at 10 kpa (1.5 psi) and I need to power it from 12v DC, 10A max. The project is in prototype stage and I will probably make a unit to test the idea. Whilst I know how side channel blowers work, I have no idea how to calculate the...
