Ahydraulic cylinder is to compress a car body down to bale size in 30 sec. the operation requires a 25 ft stroke and a 9500-lb force. if a 3000 psi pump has been selected and assuming the cylinder is 98% efficient find:

a) the required piston area in ft^2.

b)the required piston area in m^2.

c)the necessary pump flow rate.

d)the hydraulic horsepower delivered to the cylinder.

e)the output horsepower delivered by the cylinder to the load.

a)

b))

c)

d)Power = 14.14 hp

e)Power =13.85 hp

Explanation:

Given that

t =30 s

S= 25 ft

F= 9500 lb

P= 3000 psi  

1 psi = 6894.68 Pa

psi = pound force per inch square

a)

We know that

F = P A

9500 = 3000 A

We know that

1 inch = 0.0833 ft

b)

C)

Flow rate Q

d)

Power = P Q

Power = 10.55 KW

1 KW = 1.3 hp

Power = 14.14 hp

e)

Horsepower delivered by the cylinder to the load.= 0.98 x 14.14 =13.85 hp

the answer would be 32*f
