A 10inches thick parking structure wall has a total length of 150ft height and of 16inches.?

Question

calculate the rate of pour base on concrete pump capacity of 1250ft per hour.

Answer 1

8 minutes

Answer 2

10/12 x 150 x 16/12 = 167 cubic feet

so if the pump can pump 1250 cubic feet per hour, it would take about 8 minutes, though in practice it would be hard to pour that size of wall in 8 minutes, the 150ft length would slow things down some.
