The feed gas flow rate was adjusted with a mass flow controller and passed through a series of oxygen removal, alumina and activated charcoal traps to remove trace impurities. After leaving the reactor, the exit gas passed through a series of high and low (ambient) pressure traps to condense liquid products.

The steady state process can be defined as that process in which all the operating conditions (temperature, pressures, compositions, flow rate,...etc.) remains constant with time. In such process there is no accumulation in the system, and the equation of material balance can be written as: Figure 5: Steady state system

values of temperature, pressure, composition, flow rates, etc. are independent of time. Even though a process may be steady state, it is important to realize that temperature, flow rates, or other variables may, and typically do, change from one location to another (e.g. from one process stream to another).

Flow control valves come in all shapes, sizes, and designs. Their basic function, however, is the same—to control flow of air. Flow control valves for hydraulic systems (liquids under pressure) are of the same basic design. A typical example of a flow control valve is the simple water faucet installed in homes.

An ideal gas, C P = (7/2)R, is heated in a steady-flow heat exchanger from 70°C to 190°C by another stream of the same ideal gas which enters at 320°C.The flow rates of the two streams are the same, and heat losses from the exchanger are negligible. (a) Calculate the molar entropy changes of the two gas streams for both parallel and countercurrent flow in the exchanger.

Graphs 1 and 2 represent steady state accuracy, which more accurately corresponds to the performance of a true metering pump. Steady state accuracy can be defined as a pump's flow rate variation expressed as a ± percentage of mean delivered flow under fixed system conditions applied over the full turndown ratio of the pump.

GET PRICE >>Most secondary school textbooks, in their chapter about fluid dynamics, seem to suggest that "steady flow" and "laminar flow" are synonyms. Though I never received any fluid mechanics course when I was at the university, it's pretty obvious to me that flows can be laminar but non-steady.

Steady-State Flow. Steady-state flow refers to the condition where the fluid properties at any single point in the system do not change over time. These fluid properties include temperature, pressure, and velocity. One of the most significant properties that is constant in a steady-state flow system is the system mass flow .
