Answer:
Explanation:
Given that:
f = 250 Hz
= 2%
= 600 Hz
= 0.5 to 1.5 increment by 0.05
For 250 Hz = 250 cycle/sec
M = 0.98 , 1.02
At 0.7183 value of damping ratio the error value was 2% at 0.98 value of M
At 0.6330 value of damping ratio the error value was 2% at 1.02 value of M.
Hence, the damping ratio of the transducer must be placed between 0.6330 to 0.7183
Take caution, and slow down, it could run out in the middle of the road. Try going around it if possible.
Answer:
0.45516
Explanation:
ENTROPY : Entropy is a measure of molecular disorder it is denoted by S. Entropy is also measured in terms of thermal energy and temperature it is equal to thermal energy per unit temperature.
from the table S₁=1.99194 KJ/kg.k (at 400k)
from the table S₂=2.21952 KJ/kg.k (at 500k)
so total entropy change is given by =m (S₂-S₁)
=2(2.21952-1.99194)
=0.45516
