Problem 8) a certain process requires 2.3 cfs of water to be delivered at a pressure of 30 psu. this water comes from a large diameter supply main in which the pressure remains 60 psi. if the galvanized iron pipe connecting the two locations is 200 ft long and contains six threaded 90° elbows, determine the pipe diameter. elevation differences are negligible.

answer: i pick a

explanation:

a displacement distance is size of displ

an electric circuit

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
