Answer:
d. 41.4
Explanation:
The initial diameter di = 100mm
The initial height hi {✓59m
Final height = 25 m
Final diameter = ?
Initial volume = after forging volume
D*(di)²*hi = D *(df)²*hf
D will cancel out from either sides of the equation
100² x 50 = df²x25
10000x2 = df²
20000 = df²
df = √20000
df = 141.42mm
Change in diameter = 141.42-100
= 41.42
The percentage change = 41.42/100*100
= 41.4%
The last option is the answer
Answer:
Check the explanation
Explanation:
The transferred energy calculations can be done using the equation:
This is when:
• power is calculated in watts (W)
• energy is calculated in joules (J)
• time is calculated in seconds (s)
it can also be calculated by utilizing the same equation but with different units:
• when energy is measured in kilowatt-hours (kWh)
• when power is measured in kilowatts (kW)
• and when time is measured in hours (h)
kindly check the comprehensive step by step calculation to the question in the attached images below
Answer:
i)ω=3600 rad/s
ii)V=7059.44 m/s
iii)F=1245.8 N
Explanation:
i)
We know that angular speed given as

We know that for one revolution
θ=2π
Given that time t= 2 hr
So
ω=θ/t
ω=2π/2 = π rad/hr
ω=3600 rad/s
ii)
Average speed V

Where M is the mass of earth.
R is the distance
G is the constant.
Now by putting the values


V=7059.44 m/s
iii)
We know that centripetal fore given as

Here given that m= 200 kg
R= 8000 km
so now by putting the values


F=1245.8 N
Answer:
(a) Rate of heat transfer = 34.65 W/m
(b) quality of outlet of pipe x = 0.967
(c) Temperature of outer surface of insulation, T₂ = U1.157°C
Yes it is safe to touch, (But gentle touch)
