Yes, the mass flow rate can change in a closed system. This can occur due to changes in temperature, pressure, or the addition/removal of substances within the system.
The mass flow rate can be affected by factors such as the size and shape of the system, the density and viscosity of the substance flowing through the system, and the presence of any obstructions or restrictions in the flow path.
The mass flow rate is calculated by multiplying the density of the substance by the velocity of the flow and the cross-sectional area of the flow path. This can be expressed as the equation: mass flow rate = density x velocity x area.
Yes, the mass flow rate can be increased or decreased by changing the velocity of the flow, altering the density of the substance, or adjusting the size of the flow path. Additionally, adding or removing substances from the system can also affect the mass flow rate.
The mass flow rate can impact the efficiency of a system by affecting the rate at which substances are transported through the system. A higher mass flow rate can result in faster processing times and increased productivity, while a lower mass flow rate may lead to longer processing times and decreased efficiency.
