The prandtl number, npr, is a dimensionless group important in heat transfer calculations. it defined as cuk, where c, is the heat capacity of a fluid, u is the fluid viscosity, and k is the thermal conductivity. for a particular fluid, c, = 0.583 j/(g.°c), k = 0.286 w/(m: °c), and 1936 lb./(ft·h). estimate the value of npr without using a calculator (remember, it is dimension less), showing your calculations; then determine it with a calculator.

The Prandlt number for this fluid is 1630.

Explanation:

The Prandlt number is defined as:

To compute the Prandlt number for this case, is best if we use the same units in every term of the formula.

Now that we have coherent units, we can calculate Pr

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
