1 points A beam of electrons is injected between two parallel metallic plates separated by a distance d = 1 mm (Figure 1). A 35 T magnetic field is generated between the two plates in such a way that it produces a magnetic force on the electrons opposite to the electric force. What should be the potential difference in volts) between the two plates to allow an electron of 1.0x10 m/s speed to travel without deflection? X x X X...

(b) Figure Q2b shows two parallel plates with h apart, where an incompressible fluid is injected into the tiny holes as shown. Assume total volume flow rate injected is Q and width of the plates is w. The fluid is only flowing horizontally between the two parallel plates. Gravitational force may be neglected. Obtain an expression for the pressure variation using the control volume method. Provide explanation as you show your steps. (29 marks) V(x) Pi Q Figure Q2b

2. A tape is located between two parallel plates moving in opposite directions (see figure). A tape separates two fluids with different viscosity (u, = 1 mPas, uz = 5 mPa s). The distance between the plates is H = 5 cm and the tape is not subjected to any external force. (a) Determine the value of h if the tape is not moving. (b) Determine the tape velocity if h = 2.5 cm, its surface area is A =...

An incompressible, viscous fluid is placed between horizontal, infinite, parallel plates as shown below. The two plates move in opposite directions with constant velocities U 10 m/s and U2 = 5 m/s as shown. The pressure gradient in the x direction is zero and the only external force is gravity (in the y-direction). Use the Navier-Stokes equations to determine where the fluid velocity is zero (in terms of a fraction of b, i.e. 0.75 for y-75% of b) Enter Number...

In an electron microscope, there is an electron gun that contains two charged metallic plates 3.15 cm apart. An electric force accelerates each electron in the beam from rest to 8.20% of the speed of light over this distance. (Ignore the effects of relativity in your calculations.) (a) Determine the kinetic energy of the electron as it leaves the electron gun. Electrons carry this energy to a phosphorescent viewing screen where the microscope's image is formed, making it glow. ______________J...

Question 5 [20 marks) Consider Coutte flow, which occurs when we have a fluid suspended between two parallel plates, one of which is moving and the other of which is stationary. The velocity profile between these two plates is linear. We have water between these two plates and distance separating them of 1 mm. Given this information: (a) What is the force exerted on the stationary plate per m2 if the moving plate has a velocity of 0.1 m/s in...
