A solar thermal power tower is rated to produce 10 MW of power using a steam turbine. The thermal energy will be collected using 1 106 kg of molten nitrate salt as the thermal reservoir with a heat capacity of 1.5 kJ/kg K. The salt can be heated to a maximum of 565 oC and heat can be removed from the salt to a minimum of 265 oC

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.
