Given that 10000cm^3 of a fluid flows through a 2cm diameter pipe in 10 minutes:
(a) Find the fluid rate of flow in cubic meters per second.
(b) Calculate the speed of fluid in meters per second.
(c) Given that the temperature is 20°c and the Reynolds number per unit density is 1.060m^3/Kg, is the fluid more likely to be glycerin or water? (hint: calculate the viscosity of the fluid and compare it with that of the fluids at 20°c).
(d) State whether or not the fluid is turbulent

8.29 two streams containing pyridine and acetic acid at 25°c are mixed and fed into a heat exchanger. due to the heat-of-mixing effect, it is desired to reduce the temperature after mixing to 25°c using a stream of chilled ethylene glycol as indicated in the diagram. calculate the mass flow rate of ethylene glycol needed. the heat capacity of ethylene glycol at these conditions is approximately 2.8 kj/(kg k), and the enthalpy change of mixing (δmixh) is given below.
