Answer:
50,625kg of wood
Explanation:
Power input = power output ÷ efficiency
Power output = 7500 horsepower = 7500×750W = 5625000W, efficiency = 6% = 0.06
Power input = 5625000/0.06 = 93750000W
Energy input = power input × time
time = 3hour = 3×3600 = 10800sec
Energy input = 93750000 × 10800 = 1.0125×10^12J
Mass = Energy ÷ Energy density = (1.0125×10^12J) ÷ (20×10^6J/kg) = 50,625kg of wood
Answer:
Explanation:
Considering the flow of mercury in a tube:
When it comes to laminar flow of mercury, the thermal entry length is quite smaller than the hydrodynamic entry length.
Also, the hydrodynamic and thermal entry lengths which is given as DLhRe05.0= for the case of laminar flow. It should be noted however, that Pr << 1 for liquid metals, and thus making the thermal entry length is smaller than the hydrodynamic entry length in laminar flow, like I'd stated in the previous paragraph
Complete question is;
A hot plate with a temperature of 60 °C will be cooled by adding 50 triangular profile needle blades (k = 204 W/m.K) with a length of 54 mm and diameter 10 mm. According to the ambient temperature 20 °C and the heat transfer coefficient on the surface 20 W/m².K. Calculate,
a-) Wing efficiency
b-) Total heat transfer rate (W) from the wings,
c-) Calculate the effectiveness of a wing.
Answer:
A) Efficiency = 96.05 %
B) Total heat transfer rate = 166.68 W/m
C) Wing Effectiveness = 10.42

Answer: Foundries
Explanation: Casting is the method of making the liquid material to be shaped into solid form by being poured in a mold and having a hollow cavity . The liquid then turns into a solid state and this is known as casting. the casting odd metal is usually carried out in different shapes by the help of furnaces ,gases, molds etc.This process is usually performed in the certain industries known as foundry.
