A Pitot-static probe connected to a water manometer is used to measure the velocity of air. If the de?ection (thevertical distance between the ?uid levels in the two arms) is 7.3 cm, determine the air velocity. Take the density of air to be 1.25 kg/m3.
the girl at C stands pulls the rope horizontally at a constant speed of 6 ft/s. determine how fast the boat approcahes the pier at the instant the rope lenght AB is 50 ft.
The heat transfer coefficient in the oven is 25W/m^2K. Calculate rate of heat transfer per m^2 area.
engine B is supercharged with after cooling and has cylinder inlet condition of 80c and 130 k pa to avoid knock problem it is desirable to have the air-fuel temperature at the start of combustion in engine B to be the same as in engine A calculate..
a curved nozzle assembly that discharges water to the atmosphere is shown. The nozzle mass is 4.5 kg and its internal volume is 0.002 m^3. The fluid is water. determine the reaction force exerted by the nozzle on the coupling to the inlet pipe.
A long electric wire of radius r0 generates heat at rate of q'''. The surface is maintained at uniform temp of T0. Write heat equation and boundary conditions for steady state one dimensional conduction.
Calculate the pressure of 15.0g of methane gas in a 1.50L vessel at 45.0 degrees C using (a) the Ideal Gas Law and (b) the van der Walls equation using the following information about the constants, a and b: a = 2.253 and b = 0.04278.
How may data be managed to support a function (billing, human resources, accounting, finance, sales/marketing, training)?
A 0.4 W cylindrical electronic component with a diameter of 0.3 cm and length 1.8 cm is mounted horizontally on a circuit board. To cool the component air is flowing across the board at a velocity of 150 m/min. If the air temperature is T∞= 45°C, ..
What are the design implications for the location and positioning of solar cells? Explain why the use of solar cells might be more appropriate in some regions of the country.
Energy in the home, personal energy use and home energy efficiency. Efficient use of ‘waste' heat and renewable heat sources.
A piston-cylinder device contains 0.8kg of steam at 300 degrees C and 1 MPa. Steam is cooled at constant pressure until one-half of the mass condenses.
