Question

A large diameter closed top tank is filled with a depth of 3 meters of a fluid (density 1200 kg/m3). A small pipe leading from the bottom of the tank must carry the fluid some height above the fluid level in the tank. a) If a pressure of 2.5 Atmospheres is maintained in the space above the fill line in the tank how high above the fill line can the pipe carry the fluid and still provide an exit speed of 2 m/sec for the fluid out of the pipe? (the pressure at the exhaust end of the pipe is 1 atmosphere or about 1 x 105 pascal) 15 pt If the pipe diameter is 2 cm, what will be the volume rate of flow (m3 /sec) 5pt Upload Flag this Question

Question 220 pts A stretched string and an air column which is open at both ends are in resonance with each other. The air column is 55 cm. long, filled with air at room temperature (speed is 340 m/s), and is vibrating at its 3rd harmonic frequency. The string is 60 cm. long and has a total mass of 5 grams. If the string is vibrating in it's 4th harmonic frequency (and this matches the pipe’s third harmonic) a) what is the fundamental frequency of the vibrating air column in the pipe? 10pt b) what is the speed of the wave in the string? 5pt c) what is the tension in the string?

You are traveling north on a highway moving at 23 m/sec. A police car is traveling toward you going south. The approaching police car's siren is blaring and you hear a 620 Hz tone but you know that the standard siren uses a 510 Hz tone. a) how fast must the police car be moving? 10 pt b) what frequency will you "hear" after the cop passes and continues moving east at the same speed.
