Expert Solution

Answer to Problem 34E

  k=0.08hp/knots3

Explanation of Solution

Given:

  p=80hps=10knots

Concept used:

  P=ks3

P = Power

S = speed

K=proportionality constant

Calculation:

  P=ks3

P = Power

S = speed

K=proportionality constant

By using formula

  p=80hps=10knotsP=ks380=k×103k=0.08hp/knots3
