Answer:
b) Endothermic Chemical Reactions in a solid
Explanation:
Endothermic reactions consume energy, which will result in a cooler solid when the reaction finishes.
Answer:
Power output,
Given:
Pressure of steam, P = 1400 kPa
Temperature of steam,
Diameter of pipe, d = 8 cm = 0.08 m
Mass flow rate,
Diameter of exhaust pipe,
Pressure at exhaust, P' = 50 kPa
temperature, T' =
Solution:
Now, calculation of the velocity of fluid at state 1 inlet:
Now, eqn for compressible fluid:
Now,
Now, the power output can be calculated from the energy balance eqn:
<u>Explanation:</u>
Task 1 time period = 200ms, Task 2 time period = 300ms
Task ticked = → 5 times
Task 2 ticked = → 3 times
At 600 ms → 200ms 200ms 200ms
300ms →
Largest time period = H.C.M of (200ms, 300ms)
= 600ms
Answer: 78.89%
Explanation:
Given : Sample size : n= 1200
Sample mean :
Standard deviation :
We assume that it follows Gaussian distribution (Normal distribution).
Let x be a random variable that represents the shaft diameter.
Using formula, , the z-value corresponds to 2.39 will be :-
z-value corresponds to 2.60 will be :-
Using the standard normal table for z, we have
P-value =
Hence, the percentage of the diameter of the total shipment of shafts will fall between 2.39 inch and 2.60 inch = 78.89%
