Answer: (B) 100
Explanation:
Given that;
Pstatic = 20 psig , hz = 160ft, hf = 20ft
Now total head will be;
T.h = hz + hf
T.h= 160 + 20
T.h = 180ft
Minimum pressure = Psatic + egh
we know that specific weight of water is 62.4 (lb/ft3)
so
P.min = (20 bf/in² ) + (62.4 b/ft³ × 180 fr
P.min = (20 bf/in² ) + ( 62.4 × 180 × 1 ft²/144 in²)
P.min = 20 + 78
P.min = 98 lbf/in²
Therefore the minimum pressure rating (psi) of the piping system is most nearly B) 100
Answer:
Explanation:
Given that
We know that
Rex=ρvx/μ
So
All other quantities are constant only x is a variable in the above equation .so lets take all other quantities as a constant C
We also know that
Nux=hx/K
m is the constant
This is local heat transfer coefficient
The average value of h given as
---------1
The value of local heat transfer coefficient at x=L
-----------2
From 1 and 2 we can say that
Answer:
Sense the current leakage
Trip the circuit
Cut off the electricity
Explanation:
The correct order is -
Sense the current leakage
Trip the circuit
Cut off the electricity
Reason -
First step has to be taken to sense the electric current leakage without it being detected, it cant be dealt with.
The second step consists of tripping the circuit so at to remove the flow of electricity.
The third step is to Cut the electricity off so to stop the leakage and be safe.
