Thermal and differential flow meters can measure the air flow rate in most of the operating conditions. Coriolus and vortex shadding flow meters can also be used in some specific operating considitions to measure the air flow rate. Hoever magnetic flow meter can only be used to measure the liquid flow rate.
hence option A,B,D & E must be correct.

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...

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...

DESCRIPTION: The total pressure of a flow decreases along a streamline due to losses associated with non-ideal affects. These losses can be broken into major and minor total pressure losses. In this experiment, the major and minor total pressure losses through a pipe outfitted with a gate valve will be determined using pressure taps drilled into the pipe surface. The total pressure losses will be used to calculate the flow's friction factor and the valve's loss coefficient for a variety...

2 A paint sprayer pumps air through a constriction in a 0.025- m diameter pipe, as shown in the figure. The flow causes the pressure in the constricted area to drop and paint rises up the feed tube and enters the air stream. The speed of the air stream in the 0.025-m diameter sections is 5.00 m/s. The density of the air is 1.29 kg/m3, and the density of the paint is 1200 kg/m3. We can treat the...
