1.What type of pump should be used to pump water at a rate of 32 cfs and under a head of 30 ft?
Assume n=1500rpm
2.A 2 kg block is projected up a frictionless plane with and initial speed of 8 m/s. The plane is inclined upward at 30°. If the block travels 5 m before striking a linear spring, what should the spring stiffness be if the spring compression is to be limited to 10 cm.
