By Gauss Law for electric field:
Where is the charge density Q/A. Since we have 2 parallel plates with different charge, the electric field at point P in the gap would be the sum of 2 field
The formal procedure for taking equipment out of service and ensuring it cannot be operated until an authorized person has returned it to service is
Explanation:
Answer:
Piston movement of TDC to BDC is called stroke.
Explanation:
Step1
In any engine fuel is burned inside the cylinder and forces the piston to move from top dead center to bottom dead center. First piston is moved from top dead center to bottom dead center to allow the suction of fuel inside the cylinder. Then piston move toward top dead center and compresses the fuel. This process is called compression of fuel. Then fuel is burned with the spark inside the cylinder and the piston moves toward bottom dead center. This process is called expansion process. Last process is the expansion process that allows the exhaust out of the cylinder.
Step2
The piston reciprocates from bottom position of the cylinder to top position of the cylinder and vice versa. So, the motion of piston from top center to bottom center is called stroke. One movement of piston from TDC to BDC is called one stroke. There are total four strokes in petrol engine and diesel engine. So, two strokes are equal to one cycle or one rotation of crank and four strokes are equal to two rotation of crank.
Thus, piston movement of TDC to BDC is called stroke.
Answer:
Explanation:
We know that
Thermal resistance due to conductivity
Thermal resistance due to heat transfer coefficient
We know that heat transfer Q
Q=ΔT/Rth
By equating heat
Now by solving we get
