A solution of 5% NaCl in water is flowing in a stainless steel pipe. To estimate the flow rate, one of your colleagues starts pumping a 30% NaCl tracer solution into the pipe at a rate of 80mls-1 while you measure the concentration of NaCl downstream after the solutions are well mixed. If the downstream NaCl concentration is 9.5%, use mass balance principles to determine the flow rate of the initial 5% NaCl solution.

A 10 m long stainless steel (AISI 347) pipe is delivering saturated liquid water at 140 °C. The inner and out diameter is 20cm and 22cm, respectively. Ambient air at 27 °C flows over this pipe as cross flow at 5 m/s. The convection heat transfer between internal surface and water is 200W/m^2*K. If you need the external surface temperature in finding property of air, you can assume the pipe external surface temperature is 127 °C. (1) Find the heat...

L 2. Steady statemass balance: Water is flowing at steady state in a 0.1 meter-diameter pipe with a maximum velocity (turbulent profile) of 0.3 meters/sec. The pipe then goes through an expansion, to where it is then flowing in a 0.5 meter-diameter pipe, and the flow regime has changed from turbulent to laminar. In the second section of pipe, calculate the velocity as (a) block flow profile (Vavg), and (b) maximum velocity in laminar flow profile? HINT: you will need...

A water stream flowing in a pipeline is to be disinfected with chlorine. Question 1 (5 points): Experiments conducted in a laboratory in a jar test (batch reactor) have shown that the initial concentration of bacteria was reduced by 99.5% after 10 minutes. Assuming Chick’s law is valid (that is first order kinetics) compute the first order kinetics rate constant (k). Question 2 (15 points): The pipeline diameter is 0.6 m and the wastewater flow rate is 0.044
