Answer:
a) Zero
b) the rate of entropy generation in the system's universe = ds/dt = 0.2603 KW/K
Explanation:
a) In steady state
Net rate of Heat transfer = net rate of heat gain - net rate of heat lost
Hence, the rate of heat transfer = 0
b) In steady state, entropy generated
ds/dt = - [ Qgain/Th1 + Qgain/Th2 - Qlost/300 K]
Substituting the given values, we get –
ds/dt = -[5/1500 + 3/1000 – (5+3)/300]
ds/dt = - [0.0033 + 0.003 -0.2666]
ds/dt = 0.2603 KW/K
The use of smart cranes doesn't enable transportation companies to: B. Manually load or unload crates onto a train with several workers.
<h3>What is a
smart crane?</h3>
A smart crane can be defined as a mechanical equipment that is designed and developed to automatically load, unload, or control the movement of heavy equipment (objects) from one point to another, especially through the use of a projecting arm or beam.
<h3>The use of smart cranes.</h3>
Generally, various transportation companies use a smart crane to achieve and perform the following tasks:
- An ability to hire fewer workers to transport crates onto trains or haulage vehicles.
- An ability to control the movement of heavy objects.
- An ability to incorporate technological advancements into their routine work or daily practices.
Hence, the use of smart cranes by transportation companies completely abolishes the need to manually load or unload crates onto a train with several workers.

Answer:
Between 5 & 10 MPa in Table B.1.4
Explanation:
150F = 65°C
State 1:
T = 65°C , x = 0.0; Table B.1.1: v = 0,001020 m^3
/kg
Process: T = constant = 65°C
State 2:
T, v = 0.99 x v
f (65°C) = 0.99 x 0,001020 = 0.0010098 m^3
/kg
Between 5 & 10 MPa in Table B.1.4
Answer:
a) hmax = 13334.65 w/m²k
b) t = 0.288 s
c) t = 0.693 s
d) Q = 6032.37 w = 6.032 kw
