Answer:
86584N
132.306 mm
Explanation:
Q = 274
Modulus of elasticity = 118 gpa
1.
Area = 316mm² without plastic deformation
F = QA
= 274x10⁶x316x10^-6
= 274000000 x 0.000316
= 86584 N
This is the maximum load.
2.
Max length =
L = 132(1 + 274x10⁶/118x10⁹)
L = 132(1+274000000/118000000000)
L = 132(1+0.002322)
L = 132(1.002322)
L = 132.306
This is the maximum length to which it may be stretched without causing plastic deformation.
Answer:
The volumetric flow rate through the slot is 0.05472 m^3/s
Explanation:
Volumetric flow rate = peak velocity × slot width × slot height
Peak velocity = 0.8 m/s
Slot width = 114 mm = 114/1000 = 0.114 m
Slot height = 0.6 m
Volumetric flow rate = 0.8 m/s × 0.114 m × 0.6 m = 0.05472 m^3/s
Answer:
A combination square is a multi-use measuring instrument which is primarily used for ensuring the integrity of a 90° angle, measuring a 45° angle, measuring the center of a circular object, find depth, and simple distance measurements. It can also be used to determine level and plumb using its spirit level vial.

Answer:
12.332 KW
The positive sign indicates work done by the system ( Turbine )
Explanation:
Stagnation pressure( P1 ) = 900 kPa
Stagnation temperature ( T1 ) = 658K
Expanded stagnation pressure ( P2 ) = 100 kPa
Expansion process is Isentropic, also assume steady state condition
mass flow rate ( m ) = 0.04 kg/s
<u>Calculate the Turbine power </u>
Assuming a steady state condition
( p1 / p2 )^(r-1/r) = ( T1 / T2 )
= (900 / 100)^(1.4-1/1.4) = ( 658 / T2 )
= ( 9 )^0.285 = 658 / T2
∴ T2 = 351.22 K
Finally Turbine Power / power developed can be calculated as
Wt = mCp ( T1 - T2 )
= 0.04 * 1.005 ( 658 - 351.22 )
= 12.332 KW
The positive sign indicates work done by the system ( Turbine )
