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 %.

Answer:
Answer for the question:
1. A compressed air system consists of a compressor and receiver, 1500 ft of 4-in pipe, two gate valves, six standard elbows, and a manifold. Four rock drills requiring 200 cu-ft/min each are connected to the manifold by 1.25-in hoses 100 ft long. Pressure drop in the manifold is 3 psig and line leakage is 5%. Determine the pressure at the drill when all four drills are operating simultaneously and receiver pressure is 100 psig.
is explained in the attachment.
Explanation:
Answer:
The initial temperature will be "385.1°K" as well as final will be "128.3°K".
Explanation:
The given values are:
Helium's initial volume, v₁ = 6 m³
Mass, m = 1.5 kg
Final volume, v₂ = 2 m³
Pressure, P = 200 kPa
As we know,
