Explanation:
Answer:
q=39.15 W/m²
Explanation:
We know that
Thermal resistance due to conductivity given as
R=L/KA
Thermal resistance due to heat transfer coefficient given as
R=1/hA
Total thermal resistance

Now by putting the values


We know that
Q=ΔT/R


So heat transfer per unit volume is 39.15 W/m²
q=39.15 W/m²
Correct answer is option E. No dimensions
As we know formula Pressure (P) is
also,
- Dimensional formula of <em>Pressure is </em>

- Dimensional formula of <em>length is L </em>
- Dimensional formula of <em>mass is M</em>
- Dimensional formula of <em>velocity is </em>

So, as given W=
Dimensional formula of W =
since all terms get cancelled
Work is dimensionless i.e no dimensions

Answer:
The answer to this question is 1273885.3 ∅
Explanation:
<em>The first step is to determine the required hydraulic flow rate liquid if working pressure and if a cylinder with a piston diameter of 100 mm is available.</em>
<em>Given that,</em>
<em>The distance = 50mm</em>
<em>The time t =10 seconds</em>
<em>The force F = 10kN</em>
<em>The piston diameter is = 100mm</em>
<em>The pressure = F/A</em>
<em> 10 * 10^3/Δ/Δ </em>
<em> P = 1273885.3503 pa</em>
<em>Then</em>
<em>Power = work/time = Force * distance /time</em>
<em> = 10 * 1000 * 0.050/10</em>
<em>which is =50 watt</em>
<em>Power =∅ΔP</em>
<em>50 = 1273885.3 ∅</em>
Answer:

Explanation:
From the question we are told that:
Water flow Rate 
Initial Temperature 
Final Temperature 
Let
Specific heat of water 
And


Generally the equation for Heat transfer rate of water
is mathematically given by
Heat transfer rate to water= mass flow rate* specific heat* change in temperature



Therefore
