Answer:
Volumetric flow rate: Q = 1000 L/s
Step-by-step explanation:
Volumetric flow rate, also called the rate of fluid flow, is described as volume of fluid that passes a particular point per unit time. The SI unit of volumetric flow rate is m³/s.
Whereas, mass flow rate is defined as the mass of substance that passes through a point per unit of time. SI unit is kg/s.
Given- mass flow rate: ṁ = 1 kg/s and density: ρ = 1 kg/m³
Therefore, volumetric flow rate can be calculated by

Since, 1 m³/s = 1000 L/s
Therefore, volumetric flow rate: Q = 1 m³/s = 1000 L/s
