    Velocity of acoustic streaming was measured by a particle image velocimetry (case of water) and dynamic pressure technique. Based on the results obtained, a mathematical model of acoustic streaming was developed and incorporated into a commercial CFD code to characterize the mixing and flow pattern in the molten aluminum bath.

    Concrete mixing - by hand, machine or using ready mix

    Mixing concrete by hand . Typically in the UK, concrete is hand mixed 'on the deck' (i.e. the ground), generally using either a slab of existing concrete or a large mixing board - both of which can easily be hosed down and cleaned off afterwards.

    CONCRETE MIXING RATIOS - WHAT IS THE BASIC MIXING RATIO FOR

    The less water you use to mix the concrete (somewhat dry but workable) the stronger the concrete mix. Accurate concrete mixing ratios can be achieved by measuring the dry materials using buckets or some other kind of measuring device. By measuring the mixing ratios you will have a consistent concrete mix throughout your entire project.
