Explanation:
Answer:
Percentage change 5.75 %.
Explanation:Given ;
Given
Pressure of condenser =0.0738 bar
Surface temperature=20°C
Now from steam table
Properties of steam at 0.0738 bar
Saturation temperature corresponding to saturation pressure =40°C
So Δh=2573.5-167.5=2406 KJ/kg
Enthalpy of condensation=2406 KJ/kg
So total heat=Sensible heat of liquid+Enthalpy of condensation

Total heat =4.2(40-20)+2406
Total heat=2,544 KJ/kg
Now film coefficient before inclusion of sensible heat



Now film coefficient after inclusion of sensible heat



=5.75 %
So Percentage change 5.75 %.
A single car has about 30,000 parts, counting every part down to the smallest screws
Answer:
The shaft work generated per kilogram is 
Explanation:
Given:
Temperature
K
Initial Pressure
MPa
Final pressure
MPa
From the table superheated,
and

Work done by shaft is,



But here efficiency is 0.56,
So work generated per kg is,
Work = 
Work =

Therefore, the shaft work generated per kilogram is
