Liquid toluene is flowing through a pipe at rate of 175 m^3/h?

Question

what is the mass flowrate of this stream in kg/min?

Answer 1

multiply by the density of liquid toluene in kg/m^3, then multiply by 60 to convert from hour to minutes.

Answer 2

The mass flowrate is dependent on the density, which will vary somewhat with temperature.

The wikipedia gives the density of toluene at .8669 gm/ml at standard conditions.

since there are a 1000 gm in a kilogram and a million ml in a cubic meter

.8669 gm/ml is the same as 866.9 kg/m^3

so, 175 m^3/hr * 866.9 kg/m^3 = 151708 kg/hr

or 2528 kg/min

that is a very big flowrate of toluene.

be careful
