The important difference between wiring panels in series or in parallel is that electrically it affects the voltage and amperage of the resultant circuit.
In a series circuit you sum the voltage of each panel to get the overall voltage of the array. However, the amperage of the overall circuit stays the same stays the same.
The breaking fluent would squirt out
Answer:
Explanation:
The complete detailed explanation which answer the question efficiently is shown in the attached files below.
I hope it helps a lot !
Answer:
a) The exit temperature is 39.25°C
b) The highest component surface is 132.22°C
c) The average temperature for air equal to 35°C is a good assumption because the air temperature at the inlet will increase due to the result in the heat gain produced by the duct and whose surface is exposed to a flow of hot.
Explanation:
a) The properties of the air at 35°C:
p = density = 1.145 kg/m³
v = 1.655x10⁻⁵m²/s
k = 0.02625 W/m°C
Pr = 0.7268
cp = 1007 J/kg°C
a) The mass flow rate of air is equal to:

The exit temperature is:
°C
b) The mean fluid velocity is:

The hydraulic diameter is:

The Reynold´s number is:

Assuming fully developed turbulent flow, the Nusselt number is:


The highest component surface temperature is:
°C
Answer:
Advantages
The main advantage in the use of pulleys is that the effort becomes less as compared to the normal lifting of the weights. In other words, it reduces the amount of actual force required to lift heavy objects. It also changes the direction of the force applied. These two advantages in the use pulleys make them an important tool for heavy lifting. It also provides a mechanical advantage.
The other advantage in the use of pulleys is that the distance between the operator and weight. There is a safe distance between them which avoids any disaster. Pulleys are easy to assemble and cost-effective. The combination of different directional pulleys can change the position of the load with little effort. Though there are moving parts in the pulley system they require less or no lubrication after installation.
Disadvantages
Apart from the above-said advantages while using pulley systems, there are several disadvantages in their use. The main disadvantage in the use of the pulley system is that it requires large space to install and operate. The mechanical advantage of pulleys can go to higher values but need more space to install them.
In some cases, the ropes/belts move over the wheel with no grooves, the chances of the slip of ropes/belts from the wheel are inevitable. If the system is installed to use for a long time, they require maintenance and regular check-up of ropes/cables as the friction between the wheels and cables/ropes occur causing wear and tear to them. Continuous use of the system makes the ropes weak. The rope may break while using the system causing damages to the operator, surrounding place and the load which is being lifted.
