5. What is a peak flow meter and how is it used?
5. A venturi flow meter is to be used to measure the flow of air at low velocities, with air mass flow rate being given by 11/2 CA 2P (p2) RTPP2) where C is an empirically determined discharge coefficient, A is the throat flow area, pi and pp are the upstream and throat pressures, Ti is the absolute upstream temperature, and R is the gas constant for air. We want to calibrate this meter and to determine C to within...
4. A Diff. Pressure flow meter is calibrated to measure the flow of gas within 10 – 40 kg/min. the flow meter is designed to give 5 – 15 KPa differential pressure. And the meter 4-20 mA signal is designed to be linear with flow. (6) a. Find the pressure difference and the current at 20kg/min flow? b. Find the flow at 7 KPa pressure difference?
how do I find out what percent of a meter is 5 centimeters and what the percent of a meter is 5 millimeters ?
What is a laparoscope and how is it used ? How has it changed modern surgery ?
Fluid mechanics:A large tank is used to calibrate the reading from a flow meter. Measurements of the system weight as a function of time are made. Water enters the tank verticallyfrom the flow metering system at a speed of 20 ft/sec through a 1.5 in. diameter pipe. If the weight of the empty tank is 50 lbs, determine the scale reading at t=10sec. What is the true weight of the water and tank at 10 sec?
Question 2: daily peak flow of crude s r screen is installed in a wastewater treatment plant receiving a daily peak flow of crude sewage of 50000 m3. The folowing information are available - Desired velocity through screen at peak flow 0.8 m/s. 5 em clear spacing Using rectangular steel bars with I cm width, 1 m height and placed at - The inclination of screen to horizontal is 90. Estimate the a) net area of screen openings in m2...
Q6. marks) Consider an electromagnetic flowmeter which is used to measure the average volumetric flow rate of a process fluid in pipe of 0.1 m diameter. The velocity profile is symmetrical and can be assumed uniform. The flux density in the liquid is 1.4 Wb/m2. The output from the fow meter is given to an amplifier of gain 10 and the internal resistance developed due to the fluid between the electrodes is found to be is 200 kf2. The input...
A venturi meteris used to measure the flow speed of a fluid in a pipe. The meter is connected between two sections of the pipe (Fig. 14-55); the cross-sectional area A of theentrance and exit of the meter matches the pipe's cross-sectional area. Between the entrance and exit, the fluid flows from the pipe with speed V and then througha narrow ''throat'' of cross-sectional area a with speed v. A manometer connects the wider portion of the meter to the...
Air flow at 30oC through a 2cm diameter pipe is metered by a thermal mass flow meter. If 25W of energy is delivered to the meter to raise the temperature of water between the control surfaces by 1oC, calculate the mass flow rate of air. Take cp = 1006J/kgK
