A bolt is tightened, subjecting its shank to a tensile stress of 80 kpsi and a torsional shear stress of 50 kpsi at a critical p

oint. All of the other stresses are zero. The material is a brittle material with Sut =80 kpsi and Suc =150 kpsi. Find the factor of safety at the critical point by the more conservative failure theory and determine if the bolt will fracture.

Discuss the differences between conduction and convective heat transfer.
FrozenT [24]

Answer:

Basically there are two principal differences between the convection and conduction heat transfer

Explanation:

The conduction heat transfer is referred to the transfer between two solids due a temperature difference, while for, the convective heat transfer is referred to the transfer between a fluid (liquid or gas) and a solid. Also, they used different coefficients for its calculation.

We can include on the explanation that conduction thermal transfer is due to temperature difference, while convection thermal transfer is due to density difference.

A steam turbine has isentropic efficiency of 0.8. Isentropically, it is supposed to deliver work of 100 kW. What is the actual w
trapecia [35]

Answer:

80 kW; 11 kW; 8 kW; 0.6

Explanation:

Part 1

Isentropic turbine efficiency:  

\eta_t = \frac{\text{Real turbine work}}{\text{isentropic turbine work}} = \frac{W_{real}}{W_s}

W_{real} = \eta_t*W_s

W_{real} = 0.8*100 kW

W_{real} = 80 kW

Part 2

Coefficient of performance COP is defined by:

COP = \frac{Q_{out}}{W}

Q_{out} = W*COP

Q_{out} = 5 kW*2.2

Q_{out} = 11 kW

Part 3

(a)

Energy balance for a refrigeration cycle gives:

Q_{in} + W = Q_{out}

3 kW + 5 kW = Q_{out}

8 kW = Q_{out}

(b)

COP = \frac{Q_{in}}{W}

COP = \frac{3 kW}{5 kW}

COP = 0.6
