Final answer:
The mass flow rate of toluene with a volume flow rate of 175 m³/h is 2,525.83 kg/min, calculated by the product of the density of toluene (866 kg/m³) and the volume flow rate, followed by a conversion from hourly to minute rates.
Step-by-step explanation:
The student asks about calculating the mass flow rate of toluene, with a known volume flow rate of 175 m³/h. To determine the mass flow rate in kg/min, the density of toluene, which is 866 kg/m³, is required. The mass flow rate (ρQ) is the product of density (ρ) and volume flow rate (Q). Calculating this for toluene with the given flow rate:
ρQ = (866 kg/m³) × (175 m³/h) = 151,550 kg/h
To convert this to kg/min, we divide by 60 (since there are 60 minutes in an hour):
151,550 kg/h ÷ 60 min/h = 2,525.83 kg/min
Therefore, the mass flow rate of toluene is 2,525.83 kg/min.
he mass flow rate of the current can be calculated by multiplying the flow rate by the density of the liquid. In this case, the flow rate is given as 175 m³/h and the density of toluene is 880 kg/m³. To convert the flow rate to kg/min, we can divide by 60 since there are 60 minutes in an hour. Therefore, the mass flow rate is:
175 m³/h * (880 kg/m³) / 60 = 257.33 kg/min
