Take efficiency=90 %
Brake hp of pump=1.01043/0.9
=1.127 kw (or)
1.35/0.9= 1.5 hp
Other losses, take total =3 hp
Power for 3 hp pump=3*0.746=2.238 KW
Total energy the pump would consume=2.238*4 hours
=8.952 kwh/day
=9kwh/day
Total energy required =48+24+9
=81 kwh/day

=81/4=20.25 kW/hour

Gas required for power generation:
Total electricity required =81 kwh
The heat required to generate electricity=81*858*4.187=290988.126 kj/day
General efficiency=80%, thermal efficiency=25 %
Heat required =290988.126 /(0.25*0.8)=1454940.63kj/day
The calorific value of Biogas at a thermal efficiency of 60 % is =22044 kj/m3
Gas required for power generation=1454940.63/22044
=66 m3

It may be taken as 70 m3

Ancient man in search of his food had to move from one place to another place so he had to cross the obstacles which came in his way and this lead to Bridge construction. Man developed the idea of bridge construction by observing many instances from nature. For example, the development of Timber bridges can be traced the initial use of accidentally fallen trees across a stream.
