Given a DC volt meter with range 0-10V, 0-25V and 0-50V. The moving coil instrument has an internal resistor of 50Ω and full scale deflection current of 2mA. With the suitable DC

volt meter diagram, derive the equation to measure R1, R2 and R3. Also include calculation of

all the series resistors value in the circuit.​

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.
