A refrigerator has a coefficient of performance of 2.50, requires 150 W of electrical power to operate, and maintains a temperature of -4.00 °C within its interior compartment. How long would it take to cool a dozen 1.00 L of water in a plastic wrapper from 33.0 °C to -4.00 °C in this refrigerator? Any heat escaping the plastic should be ignored. Remember that 1.00 g/cm3 is the density of water.
A new building is being designed for a Bank in Colorado. The Bank's dimensions will be 180 x 340 x 14-ft high.

(b) Hairdryer is an electromechanical device that blows ambient or hot air over damp hair to speed the evaporation of water to dry the hair. To design a hairdryer, it should contain the following basic components: a duct of constant diameter with a few layers of electric coils, a small fan to pull the air in and force it through the heating coils. If the density of air is 1.18 kg/m³ at the inlet and 0.90 kg/m³ at the exit, calculate the percent increase in the velocity of air as it flows through the dryer.
AP = 5 kPa Pump The driving force for fluid flow is the pressure difference, and a pump operates by raising the pressure of a fluid (by converting the mechanical shaft work to fiow energy). A gasoline pump is measured to .consume 7 kW of electric power when operating, If the pressure differential between the outlet and inlet of the pump is measuured to be 5 kPa and the changes in yelority and elevation are negligible, determine the maximu'n possible volume flow rate of gaseline.

(a) A storage tank is connected to a piping system as illustrated in Figure P1. Water at temperature of 20°C in the storage tank flows through a piping system with the pipe's diameter of 5 cm and discharges from a nozzle to the atmospheric at velocity of 3.5 m/s. The diameter of the nozzle is 3cm. Galvanized pipe is used and installed in this piping system. All the fitting components installed in this system such as regular 90° and tees are flanged type. Water at 20°C 21 m D-5 cm d-3 cm Figure P1 i. By using suitable assumptions, predict the friction factor of this piping system (Including the Moody Chart is necessary). ii. According to the obtained friction factor in section P1(a), determine the possible pipe length of this piping system ii. After 5 years of operation, the accumulation of the dirt and other micro particles stained on the pipe's wall surface have significantly reduced the water discharge from the nozzle.
