I need the answer as soon as possible

Q4, a mechanical pump whose rated speed is (Sm=15 cfm) is connected by a pipe and valve to a vacuum vessel. If you know that the conductivity of the pipe and valve is (U=23.61/sec), write a program in C++ using the rows to find the amount of loss in a process unloading: SmU Sn Sm+U loss = Sm-Sn * 100% Sm 1 cfm = 28.3 l/ser
