Concept explainers

Speed control of motor

Speed control by DC motor-speed controller is required to realize variable speed drive. Whenever a motor drives a particular load, it is called drive, and variable speed drive refers to a load requiring variable speed. All this is obtained by a DC motor speed controller.

Two common methods of improving fuel efficiency of a vehicle are to reduce the drag coefficient and the frontal area of the vehicle. Consider a car whose width (W) and height (H) are 1.85 m and 1.70 m, respectively, with a drag coefficient of 0.30. Determine the amount of fuel and money saved per year as a result of reducing the car height to 1.55 m while keeping its width the same. Assume the car is driven 18,000 km a year at an average speed of 95 km/h. Take the density and price of gasoline to be 0.74 kg/L and $0.95/L, respectively. Also take the density of air to be 1.20 kg/m3, the heating value of gasoline to be 44,000 kJ/kg, and the overall efficiency of the car’s drive train to be 30 percent.

A building in a location is equipped with a heat pump system that is used for space heating in winter and cooling in summer. The seasonal COPs of the heat pump in winter and summer are estimated to be 2.2 and 2.8, respectively. The design heating load of the house is calculated to be 750,000 kJ/h for an indoor temperature of 25°C. The unit cost of electricity is $0.09/kWh. The annual heating degree-days in this location is 2400°C-days and the 97.5% winter design temperature is −9°C. The cooling degree-days are 1100°C-days. Determine the annual electricity consumption and its cost for heating and cooling of this house. Assume the same overall heat loss coefficient for winter and summer.
At time = 0, a constant heating power of 100 kW is applied to a boiler that intends to raise the temperature of the fluid inside to 100 ºC. The initial temperature of the fluid is 25 ºC. Temperature is taken every 2 minutes, starting at t = 0. The log after 1 hour is shown below. The x-axis is time (in minutes) while the y-axis is the temperature T. The system may be assumed to be of first order. Let θ(t) be the function describing the temperature increase, i.e. θ(t) = T(t) - 25, where T is the actual temperature.
