Question

printr un robinet curg 8,4m cubi de apa in 4 ore si jumatate.In cat timp vor curge prin acelasi robinet,cu acelasi debit 11200 litri de apa?

Answer 1

V2=11200 l=11,2 m^3

t1=4 h30min=4,5 h

Q=V1/t1=8,4/4,5=1,87 m^3/h

Q=V2/t2=>t2=V2/Q=11,2/1,87=6 h

sau

8,4 m^3...................4,5 h

11,2 m^3................... x h

x=11,2•4,5/8,4=6 h
