Answer:
545454cm
Explanation:
The blue print drawing of the house shows 666 centimeters, but the real picture of the house is 333 meters. So let the number of cm on the blueprint that represent the distance of 272727 meters be x. Firstly convert the meters to centimeters 666cm = 333m, x=272727m ; then cross multiply, 666cm=33300cm x=27272700cm ; x =(666cm×272727cm)/33300cm =545454cm.
Answer:
A pigtail when wiring is technique that is used in connecting a lot of wires together.
Explanation:
A pigtail is a wire that is short in length. It has two ends. One end has a connector while the other end has other wires connected to it.
Pigtail when wiring is the connection of more than one wire in a circuit to another device. Pigtail when wiring helps to extend the length of the wire in a circuit if the wire used it short).
Pigtail when wiring is a technique what helps to keep the circuit organised because it prevents the wires from getting tangled.
Answer:
I did not what is it about?
Answer:
a) Decrease
b) Decrease
c) Decrease
d) Decrease
Explanation:
Ti= 200°F ,
Te = 170°F
Area of heat exchanger =
= 20π
<u>A) when The flow rate of the cooling fluid is increased</u>
Temperature of process stream will decrease and this is because the tube side heat transfer coefficient will increase and this will increase the rate of heat transfer thereby decreasing the temperature of the process stream.
B) <u>when There are 200 tubes that are 1.0-in. OD and 20.0ft long</u>
The temperature of the process stream will decrease and this is because the heat transfer coefficient will increase likewise the heat transfer rate
C) <u>When The number of shell passes is doubled</u>
This will cause an increase in the overall length of the shell, an increase in velocity of constant volumetric flowrate, hence the Temperature of the process steam will decrease as well
D)<u> When The tube material is changed to copper.</u>
Due to the high thermal conductivity of copper when compared to steel , switching to copper will cause a decrease in the temperature of the process steam
