To determine

The four major factors to be considered when installing a motor control in concern with the power system.

Explanation of Solution

The electrical connections that are associated with a motor, machine, and control unit are easy or complex. However, the below-listed factors should be considered while installing a motor and its control.

  • Power source –– Check whether the motor and control unit require a single-phase or three-phase power supply with rated voltage and current.
  • Motor connections –– A motor connection should be made based on the information found on the name plate of a motor. The name plate of a motor contains information such as horsepower, service factor, voltage, and full load current rating.
  • Controller type –– In general, a motor requires simple controller that starts and stops the motor. In addition, a motor may require controllers that vary the speed of the motor at specified time, inching, and jogging.
  • Environment –– The environment should not affect a control unit. The elevated temperature and moisture may affect a control unit.

A 2-kW resistance heater wire with thermal conductivity of k=20 W/mK, a diameter of D=4mm, and a length of L=0.9m is used to boil water. If the outer surface temp of the resistance wire is Ts=110 degrees C, determine the temp at the center of the wire.
A flat-plate solar collector is used to heat water by having water flow through tubes attached at the back of the thin solar absorber plate. The absorber plate has emmisssivity and an absorptivity of 0.9. The top surface where x=0 temp of the absorber is T0=35 degrees C, and solar radiation is incident on the basorber at 500 W/m^2 with a surrounding temp of 0 degrees C. The convection heat transfer coefficient at the absorber surface is 5 W/m^2 K, while the ambient temp is 25 degrees C. Show that the variation of the temp in the basorber plate can be expressed as T(x)=-(q0/k)x+T0, and determine net heat flux, q, absorbed by solar collector.
