Everyone has experienced using a water fountain that produces a bit too much water pressure. In fact, the drinking fountain on the 3rd floor of Dana Hall at the south end of the hallway shoots a pretty good jet of water. Using a water bottle with a known volume (such as a typical 1-liter Nalgene bottle), a) determine the volume flow rate for this particular water fountain. Make additional physical measurements on the water fountain to estimate: b) the water velocity, and c) the pressure at the exit nozzle.
.Water enters a very wide rectangular channel (Manning’s n = 0.0149) at a velocity of 12.2 ms-1 and a depth of 0.61 m. An H3 curve forms downstream and the water jumps to a depth of 2.4 m some distance downstream. Find the distance downstream to the ..
A larger-diameter pipeline will cost $2.1 million installed, but its operating cost will be only $8000 per month. Which pipe size is more economical at an interest rate of 1% per month on the basis of an annual worth analysis
The coal-fired boilder supplies 70 MW to the steam while thermal energy is rejected to a nearby lake whos average temperature is 15 C. What is the minimum required temperture of the boiler to meet the power demands of the city
The drinking water needs of an office are met by large water bottles. One end of a .25 in diameter plastic hose is inserted into the bottle placed on a high stand, while the other end with an on/off valve is maintained 2 ft below th bottom of the bot..
a room having a total heat gain of 35,000 btuh is to be maintained at 80 DB and 62 WB. the air is supplied to the room at 60 DB and 55 WB. find the quanity of air to be supplied.
The investigation results indicated that the clay had a saturated density of 1.6 Mg/m3, an average initial void ratio of 1.8 and the preconsolidation pressure at the mid depth of the clay layer was 20 kPa.
find the unknown quantity in each of the following, using the standard series equivalence formulas and tables in the Appendix. Give preference to the approach yielding the fewest computational steps.
An inspector is paid $10/hr and can sort 10 rings/min. Assume that a new method allows her to sort 20 rings/min but costs $500 to implement. Is it worth implementing the new method for a batch of 50,000 rings? At what point does the new method pay of..
An Air manometer is connected to each side of an orifice, with a diameter of 8 inches, in a pipe with a diamter of 12 inches. If a maximum flow rate is 5 ft^3/s, what is the deflection of the manometer
The two shafts are made of A-36 steel. Each has a diameter of 25 mm and they are connected using the gears fixed to their ends. Their other ends are attached to fixed supports at A and B
