Horse power types
Type of horse power :-
1.Indicated horse power(I. H. P) :- It is the power that is produced inside the cylinder or motor of an engine, it is also called theoretical horsepower.
2. Brake horse power(B. H. P) :- This is the power we actually get from the engine.
3. Frictional horse power (F. H. P) :- The power lost due to friction is called friction horse power.
I. H. P = PLAN (in metric system)
4500
P = average pressure in kg/cm^2
L = length of stroke in metre
A =area of piston or cylinder in cm^2
N = r.p.m of crank shaft
I. H. P = PLAN (in British system)
3000
In four stroke engine take r.p.m =N/2
In double acting engine take r.p.m = N×2
In multi cylinder engine= I.H.P×No.of cylinder
I. H. P = B. H. P +F. H. P
B. H. P =I. H. P - F. H. P
EFFICIENCY = B. H. P ×100
I. H. P
Gravitational units -
i) m.k.s system : kgm/sec
ii) c.g.s system : gm cm/sec
iii) f.p.s system : foot pound /sec
