What would happen if an elementary student pulled a fire alarm?

Answer:

she might have just figured out she doen't have the money to pay you. Granted she could have told you that in a lot nicer way than she did, but you shouldn't get too mad at her, because im guessing she thought you'd be really mad if he told you the real reason.
when you attack a pump problem there are a few parameters you need to know. the fluidwater ,oil , asphalt etc. the static head ..that's the simple rise and the dynamic head the amount of resistance the pipe and fittings and other appurtenances have on the flow. And other thing you generally need is a rate ..In the first question power is a consumption value for me and it is wattage,which i convert to horsepower. For the person who wrote the question they may mean horsepower directly. Since a rate is not suggested just quote the formula for WHP ..The Head is the rise in feet 50 plus the friction of the pipe. the pipe is the Hypotenuse of the triangle 50 x 200..with unknown friction and diameter to answer this the rise + the friction is all you need to say. 2.vertically 200 m on the same floor..well I would bet that its horizontally on the same floor. Friction is the only head if there is no rise. quote the formula for WHP for the pump power 3.well your right the simple static head is 200m and the power is found again by the WHP formula. these are all the same thing basically getting something from one point to another through a pipe or tube. Friction ,head elbows reducers every little piece has a determining factor . Of course that's in a real situation . For your work just look at the interactive formulas i sent you substitute into them some real values and see what you get .. you'll find that regular horsepower and WHP are a little different. You'll also find out that working with pumps pipes motors and all that stuff is not nearly as hard as you might think..Have a good one from the E
