Apitot-static tube is mounted on a 2.5 cm pipe where oil = 860 kg/m3, = 0.0103 kg/m·s) is flowing. the pitot tube is positioned such that the local velocity measured is similar to the mean velocity through the pipe cross section. the pressure difference is measured to be 95.8 pa. find the volumetric flow rate in m3/s.

Explanation:

Given:

density,

diameter of the pipe,

pressure difference,

In case of  pitot tube, the velocity is given by:

Now we know that volumetric flow rate is given as:

where :

a= cross sectional area of the pipe

v= velocity of flow

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
