Tests on the flow of six different liquids in smooth pipes of various sizes yield the following data. make a dimensional analysis of this problem and a plot of the resulting dimensionless data. diameter [mm] average speed [m/s] viscosity [mpa. s] density [kg/m3 ] wall shear stress [pa] 300 2.26 862 1247 51.2 250

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

Ahe-xe mixture containing a 0.75 mole fraction of helium is used for cooling electronics in an avionics application. at a temperature of 300 k and atmospheric pressure, calculate the mass fraction of helium and the mass density, molar concentration and molecular weight of the mixture. if the cooling capacity is 10 l, what is the mass of the coolant?

The maximum shear stress and maximum flexural stress occur at the same location along a beam subjected to a non-uniform bending load. a)-trune b)- false
