Answer:
Rate of Heat Loss = 336 W
Explanation:
First, we will find the surface area of the cylinder that is modelled as the man:
where,
r = radius of cylinder = 30 cm/2 = 15 cm = 0.15 m
l = length of cylinder = 170 cm = 1.7 m
Therefore,
Now, we will calculate the rate of heat loss:
where,
h = convective heat tranfer coefficient = 15 W/m²K
ΔT = Temperature difference = 34°C - 20°C = 14°C
Therefore,
<u>Rate of Heat Loss = 336 W</u>
Option c is correct. Hole filling fasteners (for example, MS20470 rivets) should not be used in composite structures primarily because of the increased possibility of fretting corrosion in the fastener.
Fretting corrosion is the outcome of simultaneous physicochemical and mechanical surface interaction in a tribological contact, and it is the irreversible change of a material. A specific load and cyclic displacement with a limited amplitude must be applied to the contact between the surfaces of two materials for fretting corrosion to take place.
Small gaps develop between the surfaces in contact as a result of cyclic tension. Either material is lost or cracks start to appear as a result. Fretting corrosion's side effect of contact corrosion almost always causes a blockage because the lack of functional movement makes it impossible to remove debris. When debris is still trapped, there is blockage because the oxide takes up more space than the original material.

Answer:
Flow velocity
50.48m/s
Pressure change at probe tip
1236.06Pa
Explanation:
Question is incomplete
The air velocity in the duct of a heating system is to be measured by a Pitot-static probe inserted into the duct parallel to the flow. If the differential height between the water columns connected to the two outlets of the probe is 0.126m, determine (a) the flow velocity and (b) the pressure rise at the tip of the probe. The air temperature and pressure in the duct are 352k and 98 kPa, respectively
solution
In this question, we are asked to calculate the flow velocity and the pressure rise at the tip of probe
