Question

Homework 5 EET 4450 Rocket Number I. A turbine flow meter has a K value of 45 cm'Vpulse. Determine the volume of liquid transferred for the following pulse count: a. 30,060 1232-700 m/s 2. Determine the flow rate for each pulse count in question 1 (above), if the pulse counts occur during a 180 second time interval. 100 Determine the stroke of a bellows transducer if the bellows pressure element has a range spring and the following values: 3. Effective area of the bellows-15 cm2 b. Spring rate of the spring 400 N/em c. Spring rate of the bellows 25 N/cm d. Pressure range is 0 to 50 N/cm What is the stroke of the bellows? 4. Bolton chapter 2: problems 12 A displacement float level transducer has the following data. Determine the minimum and maximum values of the force applied to the beam by the float. 5. a. Mass of the floatM-605 kg b. Area ofthe float A=50 cm2 c. Length of the float L-4.0 m d. Liquid in the vessel is water

Explanation / Answer

Effective area = 15 cm2.

Equivalent spring rate = Kspring + Kbellows = 425 N/cm

Pressure range = 0 to 50 N/cm2.

Force range = P * Area = 750 N max.

Maximum stroke = Force/Spring rate = 750/425 = 1.76 cm
