If water is forced to flow in a level pipe and the pipe diameter gets smaller, the total pressure get: a. smaller
b. larger
c. constant
d. further info required

Distance^2= yellow line ^2 (see picture) = 30^2 + 49^2so distance = squareroot of (300^2 +49^2)i dont know if this is how to solve it, but i cnt think of another way

Iwould have to say sorry i can't elaborate more. hope this though!
