Q14-Calculate the heat transfer coefficient for water flowing through a 25mm diameter tube at the rate of 1.5kg/s, when the mean bulk temperature is 40 C. For turbulent flow of a liquid take;

What are the five possible feed conditions?

How did you get the overall cp value?

QUESTIONS Q1. Sodium sulphate decahydrate crystals (NażSO4.10H2O), DH are produced in a continuous vacuum crystallizer. Concentrated sodium sulphate solution from an evaporation system with a flow rate of 2000 kg/h at 80°C and 1 atm is mixed with 4000 kg/h of a saturated aqueous recycle filtrate of sodium sulphate solution at 20°C and 1 atm. The mixture is sent to the vacuum crystallizer, operating at 20°C and 50 mmHg, to produce water vapor and magma of 25 wt% crystals and 75 wt% saturated solution. The magma is then sent to a filter, from which filtrate is recycled. a) Draw a block diagram of the process. b) Define the streams and units in the block diagram. c) Mark the streams on temperature versus concentration diagram and enthalpy concentration diagram. Determine: d) crystal production rate (on a dry basis). e) evaporation rate of water in vacuum crystallizer. f) the energy required in vacuum crystallizer. 120 100 80 60 Na, so, + solution solution 40 20 Na, so, 10H,O + solution 4…

Plot the the attached data - Absorbance vs. Time When determining the slope of the line, you should omit any points from any obvious curved regions. For the uncooked sample, what is the last time point you used to determine the slope of the linear portion of the plot?
