Hi everyone

We are using Particle Image Velocimetry (PIV) camera for measuring velocity of water over spillways, in the laboratory. The problem is, we don’t have enough amount of PIV seeding particle which used for this purpose. Kindly suggest me how to get this material with the following characteristics:

1. Material: Polyamide

2. Suitable for water based flows

3. Mean diameter: Approx. 100 μm

4. Specific gravity: 0.99 g/cm3

Thanks in advance
