Answer 1

0.53Mg =

!mg = 2204.6lb

0.53Mg = 0.53*2204.6lb = 1168.44lb = 1.2*10³ lb

1.59 L/min to gal/day

1L/min = 380.408 gal/day

1.59 L/min = 1.59*380.408 gal/day

                 = 604.85gal/day   = 6.0485*10² gal/day

0.021 lbs/in3 to kg/m3

lbs/in3 = 27679.9Kg/m³     = 2.76*10⁴ Kg/m³

   0.021lbs/in3 = 0.021*27679.9Kg/m³   = 581.27Kg/m³ = 5.8*10² kg/m³
