Answer:
Explanation:
The difference between mass and weight is that mass is the amount of matter in a material, while weight is a measure of how the force of gravity acts upon that mass. Mass is the measure of the amount of matter in a body. ... Weight usually is denoted by W. Weight is mass multiplied by the acceleration of gravity (g).
Answer:
total friction is 0.9903 m
Explanation:
given data
diameter D = 100 mm = 0.1 m
discharge Q = 4 L/s = 0.004 m³/s
total length L = 300 m
roughness ∈ = 0.2 mm
solution
we get here total friction loss hf that is express as
hf = ......................1
first we get here Reynold's no that is
Re = ................2
Re =
Re = 50900
so here f is 0.025 by moody diagram
so put all value in equation 1 we get
hf =
hf = 0.9903 m
so total friction is 0.9903 m
Answer: Feeder
Explanation:
The National Electrical Code (NEC) which has been adopted by all 50 stated in the Repubic is a code that governs the installation of electrical devices, circuits and systems. The primary purpose is to safeguard the populace in the use of electricity which can prove to be hazardous if not properly used.
Article 100 of the the NEC defines a Feeder as <em>All circuit conductors between the service equipment, the source of a separately derived system, or other power supply source and the final branch-circuit overcurrent device.</em>
Answer:
118.76 kPa
Explanation:
Molar mass of CO =16+12=28
Value of R
Mass of CO that is m = 1 kg
Volume = 1
Temperature =127°C =127+273=400 K
We know the ideal gas equation
Putting all these values
P=118.76 kPa
