Mass flow rate is the mass of a substance passes per unit of time. Given below mass flow rate example problems where you can know how to find mass flow rate in kg/hour using the formula given.
Let us consider the problem: 18 kg/m3 of liquid flowing in a speed of 15 m/sec and with an area of 12 m2. Calculate mass flow rate of liquid.
We can calculate the Mass Flow Rate using the given formula.
Substituting the values in the formula,
Mass Flow Rate(kg/hour) = (15 × 12 × 18) × 3600 = 3240 x 3600 = 1166400 kg/hour
Therefore, the value of Mass flow rate is 1166400 kg/hour.
Refer the below mass flow rate calculation example problem with solution for 8 g/cm3 of air flowing in a speed of 12 m/hr and with an area of 9 cm2. Calculate mass flow rate of air.
Substituting the values in the above given formula,
Mass Flow Rate = (8 × 12 × 9) × 3600 = 864 x 3600 = 3110400 kg / hour
Therefore, Mass flow rate is 3110400 kg / hour.
