The influence of flow rate and viscosity on pumping of concrete has been confirmed. It is also shown that with a 20% decrease in pipe radius (from 125 to 100 mm), the pumping pressure can be roughly doubled. An increase in yield stress also increases the pumping pressure, but its ...

How to Work Out Watts Watts = Volts x Amps e.g. A 120 volt appliance takes 2 amps, what is the power?Power in watts = 120 x 2 = 240 watts How to Work Out Amps Amps = Watts / Volts e.g. A 240 volt appliance consumes 480 watts of power, How much current does it draw?
We’ve now got a concrete base to build from. How we achieve this depends on you as the player – nine birdies and four drop shots a round would work, however, a steady round of five birdies and no drop shots will be just as effective. ...
