Determining the time constant of the circuit
A 494-turn solenoid has a radius of 7.95 mm and an overall length of 12.4 cm.
(a) What is its inductance?
(b) If the solenoid is connected in series with a 2.50 Ω resistor and a battery, what is the time constant of the circuit?

What was the work transfer? Was the work done on or done by the system? What was the heat transfer? Was the heat added or removed from the system?
In Boulder Dam, 2000 cubic feet per second of water flows through each of the pipes (called penstocks) that lead down to the turbines. The penstocks are 30 feet in diameter, have a roughness of 1 inch and are 1000 feet long.
Air initially at rest (M1 = 0) with an initial pressure P1 = 1 atm and temperature T1= 300k flows through a nozzle into a partial vacuum with P2 = 0.2 atm. There is no elevation change. What is the air temperature at the end of the nozzle (T2)?
A mass of 12kg of refrigerant-134a initially exists as a saturated vapor in a piston-cylinder device at 240 kPa. Show the process on a P-v diagram with respect to saturation lines.
If the solenoid is connected in series with a 2.50 Ω resistor and a battery, what is the time constant of the circuit?
What types of engineers (e.g. civil, construction, mechanical, industrial, material science, electrical, etc.) do you think need to be familiar with heat transfer? Why?
An engineer needs to monitor a flow of 20°C gasoline at about 250±25 gal/min through a 4- in-diameter smooth pipe. She can use an orifice plate, a long-radius flow nozzle, or a venturi nozzle, all with 2-in-diameter throats.
The magnetic field inside a superconducting solenoid is 5.00 T. The solenoid has an inner diameter of 6.20 cm and a length of 26.0 cm. (a) Determine the magnetic energy density in the field.
