A very loud train whistle has an acoustic power output of 200 Watts. If the sound energy spreads out spherically, what is the intensity level in dB at a distance of 200 meters from the train?

a. 82 dB

b. 86 dB

c. 89 dB

d. 95 dB

e. 98 dB

Expert Solution

Option b is correct. To convert in to decibel a threshold level of hearing intensity should be considered.

Radiation force balance power meters are commonly used to measure output acoustic power of ultrasound transducers. Two types of targets are usually used in these devices: a flat perfect absorber, or a cone-shape perfect reflector. What would be the angle theta for a cone perfect reflector in order to get identical power readings for a given ultrasound exposure with two different type of targets? Assume that the two targets have equal surface areas. You must provide a proof for your...

A combined gas turbine–vapor power plant has a net power output of 200 MW. Air enters the compressor of the gas turbine at 300 kPa, 1200 K, and is compressed to 1000 kPa. The pressure ratio of the gas turbine cycle is 11. Steam leaving the turbine of the vapor power cycle are used to heat the steam at 6 MPa to 350C in a heat exchanger. The combustion gases leave the heat exchanger at 420 K. An open feedwater...

A nuclear power plant has an overall efficiency of 31% and a power output of 800MW. For one year operating at full capacity, calculate a) the number of joules produced; b) the number of fission events that were required to produce those joules; c) the mass of uranium oxide (UO2) that has been used in fission; and d) the market cost of that uranium oxide if it was all high quality.

An automobile manufacturer has offered a 6 yr / 60,000 mi. power train warranty. If the power train has a life expectancy of 61,000 mi. with a standard deviation of 8,000 mi., what is the probability that the average life of powertrains from 625 randomly selected automobiles will be fewer than 60,497.6 mi.?

A steam power plant has two turbines in series which together develop a power output of 25MW. The boiler supplies steam at 80 bar, 500°C to the high-pressure turbine in which there is an enthalpy drop of 420 kJ/kg. The exhaust from the high pressure is at a pressure of 15 bar, at which pressure some of the steam is delivered to an open-type feedwater heater while the remainder is reheated to 450°C. The steam from the reheater is expanded...
