Consider liquid water flowing over a flat plate of length L = 1 m. The water has the following properties: ρ-1000 kg/m3, Cp-4000 J/kgK. 10 3 kg/ ms, k 0.6 W/m . C μ Midway through the plate at x = 0.5 m, you measure a heat flux to the surface of: 05 m 3181 W/m2 You also measure an average heat flux to the surface over the length of the plate of: "4500 W/m2 Knowing the latter, and knowing...
A flow nozzle equipped with a differential pressure gage is used to measure the flow rate of water at 10°C (p 9997 kg/m3 and p 1.307 x 10-3 kg/m s) through a 3-cm-diameter horizontal pipe. The nozzle exit diameter is 1.5 cm, and the measured pressure drop is 3.3 kPa. Determine the volume flow rate of water, the average velocity through the pipe, and the head loss 1.5 cm Differential pressure gage -3 m3(s m/s The volume flow rate of...

i really appreciate it if explain this throughly June 1. Consider steady, fully-developed laminar flow of air through a Laminar Flow Element (LFE, a type of flow-meter) with an aligned bundle of 100 small bore tubes, each of diameter D 2.00 mm, and length L 200.0 mm. The pressure drop per unit length (Ap/L) across each of the 100 tubes is a function of the tube diameter D, fuid viscosity u (in units N s/m2), and average air velocity Vave....
