    Adding a substance to water to reduce its specific gravity for pump testing

    Thank you for the responses. In my initial research, I pretty much only found alcohols that had a low enough specific gravity that could be added to lower water's specific gravity to match diesel's. The density of the fluid involved does indeed matter in the efficiency of a jet pump. One...

    Adding a substance to water to reduce its specific gravity for pump testing

    Hello all, I am working on a project involving diesel fuel and a venturi jet pump. I would like to use a water pump with something added to the water to reduce the specific gravity of the mixture to match diesel, which has a specific gravity of 0.85. I am curious if anyone has done something...
