Explanation:
Diesel cycle:
All diesel engine work on diesel cycle .In diesel cycle there are four process .These processes are as follows
1. Adiabatic reversible compression
2.Heat addition at constant pressure
3.Adiabatic reversible expansion
4.Constant volume heat rejection
In general compression ratio in diesel engine is high as compare to petrol engine.But the efficiency of diesel cycle is less as compare to petrol cycle for same compression ratio.
Applications of diesel cycle:
Generally diesel cycle used for heavy vehicle or equipment because heavy vehicle or equipment is required high initial torque.So this cycle have lots of applications such as in industrial machining,in trucks,power plant,in mining ,in defense or military,large motors ,compressor and pump etc.

Explanation:
It will help because we can unlock new potential with electric and can help us with things we can’t do
Answer:
mechanical efficiency = 54%
Explanation:
given data
power We = 44 kW
density = 860 kg/m³
rate of flow = 0.07 m³/s
inlet diameter d1 = 8 cm
outlet diameter d2 = 12 cm
pressure = 500 kPa
efficiency η = 90%
to find out
mechanical efficiency
solution
we get here shaft power is here
shaft power = efficiency × electric power
shaft power = 0.9 × 44 = 39.6
and
now we get DEmech that is
DE(mech)= m g h + (v² - u ²) .....................1
that is we can write as
DEmech = ρVgh +
= VDP + ×
Plugging in values we now have DEmech that is
DEmech = (0.07m^3/s × 500kPa) +
solve we get
DEmech = 21342 W
DEmech = 21.3 kW
mechanical efficiency is
mechanical efficiency =
mechanical efficiency = 0.54
mechanical efficiency = 54%
