to conserve water and energy a flow reducer is installed in the shower head shown here. if the pressure at point 1
Remember that velocity is a vector quantity so find the magnitude of the average velocity and the angle of average velocity from the horizon
Create a personal checklist (below) to demonstratemethods of simplification of series-parallel circuits. Your checklist should contain the following:
A pump in a tank of water at 20°C directs a jet at 45 ft/s and 200 gal/min against a vane, as shown in Fig. P3.73.
A cold air chamber is proposed for quenching steel ball bearings of diameter D = 0.2 m and initial temperature Ti = 400°C. Air in the chamber is maintained at - 15°C by a refrigeration system
a horizontal wire of length 0.57 m carrying a current of 6.9 a is placed in a uniform external magnetic field. when the
Manganese has a density of 7.44 g/cm^3. Given that the activation energy for vacancy formation is 1.1 eV/atom, calculate the number of vacancies per cubic meter of Manganese at 1200 degrees C. The atomic weight of manganese is 54.94 amu.
The temperature in a pressure cooker during cooking at sea level is measured to be 250 F. Determine the absolute pressure inside the cooker in psia and in atm. Would you modify your answer if the place were at a higher elevation?
a house that was heated by electric resistance heaters consumed 1200 kwh of electric energy in a winter month. if this
Movement of stagnant air over a surface typically decreases the pressure that air exerts on the surface it was in contact with, and higher air velocities usually result in more significant pressure drops. This pressure drop from rapidly moving air ac..
An air nozzle has an exit area 1.6 times the throat area. If a normal shock occurs at a plane where the area is 1.2 times the throat area, find the pressure, temperature, and Mach number at the exit. The stagnation temperature and pressure before the..
