//Input data
d=10//Diameter in cm
l=15//Stroke in cm
r=6//Compression ratio
ihp=20//Indicated horse power in h.p
N=1000//Speed in r.p.m
n=4//Number of cylinders
nt=30//Thermal efficiency in percent
CV=10000//Calorific value in kca/kg
g=1.4//Ratio of specific heats

//Output

pc=(ihp*4500*60)/(427*(nt/100)*CV)//Petrol consumption in kg/hr

//Output
