Water, SAE 30 motor oil, and honey flow through three 25 cm diameter pipes. Each pipe passes a volumetric flow rate of Q = 0,01 m3/s. Assume the densi- ties of these fluids are water = 1, 000 kg/m3, oil ; 850 kg/m3, and honey = 1,300 kg/m3, and the viscosities are
water with u = 1 cP
SAE 30 motor oil with u = 200 cP
honey with u = 10,000 cP
What is the Reynolds number for each of the three flows?

I have test data for three heat shields and am looking for an explanation (one that can be supported with math theory) for why they preformed the way they did. Three samples were tested: a .063" aluminum plate and two heat
A certain industrial process requires a steady 0.75 kg/s supply of compressed air at 500 kPa, at a maximum temperature of 30C. This air is to be supplied by installing a compressor and after cooler. Local ambient conditions are 100 kPa, 20C.
A broad-crested weir is formed by cutting a rectangular notch in a 1.0-foot- thick concrete wall. The notch is 2.0 feet deep and 14.0 feet long. If an im- poundment rises up to the top of the wall, what is the discharge over the weir?
a patent application describes a device that at steady state receives a heat transfer at the rate 1 kw at a
