  • 10. A = 30 m3/menit

    B = 5/6 x 30 m3/menit = 25 m3/menit
    = 25 m3/menit : 1/60
    = 25 m3/menit x 60/1
    = 1500 m3/ jam

    sellisih A dan B =
    30 m3/menit - 25 m3/menit = 5 m3/menit

    7. a . 30 L/ menit + 8 cL/meni = 3000 cL/menit + 8 cL/menit = 3008 cL/ menit

    b. 0,8 m3/jam - 0,5 m3/jam = 0,3 m3/jam = 0,3 x 1000 dm3/3600 detik
    = 300/3600 = 1/12 dm3/detik = 1/12 L/detik

    9. debit keran ll = 2 x 1/300 m3/menit = 2/300 m3/menit
    = 2/300 x 100 dm3 : 1/60 = 2/3 x 60/1 = 40 dm3/jam = 40 Liter/ jam
