- (a) By means of (5.6.8), determine the speed of sound in distilled water at atmospheric pressure and a temperature of 30°C. (b) What is the rate of change of the speed of sound in water with respect to temperature at this temperature?arrow_forwardEstimate the speed of sound of carbon monoxide at 200-kPa pressure and 300°C in m/s.arrow_forwardConsider an airplane flying at a velocity of 250 m/s. Calculate its Mach number if it is flying at a standard altitude of (a) sea level, (b) 5 km, (c) 10 km.arrow_forward
- An aeroplane is cruising at a speed of 750 kmph at an altitude, where the air temperature is 5°C. Calculate the flight Mach number at this speed.arrow_forwardIn your own words, write a summary of the differences between incompressible flow, subsonic flow, and supersonic flow.arrow_forwardOn October 3, 1967, pilot William J. "Pete" Knight set a world record that still stands to this day for the fastest flight by a crewed, powered aircraft by flying the North American Aviation X-15 as fast as Mach 6.7 at an altitude of 102,000 ft above sea level. Mach number is the ratio of an object’s velocity to the local speed of sound. Using the table for atmospheric properties with respect to altitude, calculate the speed of sound at an altitude of 100,000 ft. What must have been the velocity of the X-15?arrow_forward
- A jet transport is flying at a standard altitude of 30,000 feet with a velocity of 550 miles per hour. What is the Mach number?arrow_forwardAt 300°C and 1 atm, estimate the speed of sound of(a) nitrogen, (b) hydrogen, (c) helium, (d ) steam, and(e) 238UF6 (k≈ 1.06).arrow_forwardWhat is the Mach Number of an air with a velocity of 250 m/s, at a temperature at 2800 meters?arrow_forward
- The sound power level of a certain jet plane flying at a height of 1,5 km is 110dB. Find the maximum sound pressure level on the ground directly below the flight path assuming that the aircraft radiates sound equally in all directions.arrow_forwardDescribe physically what the “speed of sound” represents.What kind of pressure changes occur in air sound wavesduring ordinary conversation?arrow_forwardThe question is: Calculate the velocity of sound propagating in water at 20 degrees C. Assume that the bulk modulus of water K = 2.2 X 109 Pa. I have a= square root of (K/p) I'm coming up with 1485 m/s. The answer is supposed to be 1461 m/s. What am I doing wrong.arrow_forward
