To prevent anymore animal deaths including my own last night by speeding cars in my residential neighborhood. I was playing with my dog, Buster in my front yard when he ran across the street to chase a cat then ran straight across the street and an White SUV who lives up the street from me just hit him and didn't even stop! If I would have reached for him I would have been hit too, the driver didn't see us and the street is well lit. What can I do, post signs, speed bumps, etc other than the 30mph posted signs that the neighbors down the street don't abide to? Do to this heat wave we are having kids are playing outside late evenings too and Im concerned that one could be victum to a car hitting them because of their speed. Please help.Im mourning my family petand my husband confessed last night after Buster was hit that his Best cat friend, Kitty was hit in the same spot 3 months ago..Im very upset and need direction.
We need to find the cross-sectional area of the nozzle where the water exits. We have its diameter (d) as 2.20 cm. so the area A is ? times π times d? So A (0.7854)(4.84) 3.8 sq. cm. If the water flow rate is 0.0120 cubic meters per second, that is 12 liters per second or 12,000 cubic centimeters (cc) per second. So the speed equals the volume (12,000 cc.) divided by the area (3.8 sq. cm.) or 3157.9 centimeters per second, or 31.579 meters per second. You can round it to 31.58 meters per sec.
You always use a clamp when holding tubes, and safety goggles are compulsory when heating. If the materials used react with water, rinsing with water is dangerous, but if they do not, then it is fine. Heating should be done in boiling tubes.
