Question
Chapter 7, Problem 7.8P
Interpretation Introduction
(a)
Interpretation:
The speed of head of the hammer at which it must be travelling at the moment of impact to ring the bell is to be calculated.
Concept introduction:
The kinetic energy of the hammer is calculated by the formula,
The transfer of energy from hammer to the metal ball takes place when a pedal is hit hard by a hammer. The speed of metal ball can reduce if the friction between metal ball and surface of the pole is more.
Interpretation Introduction

Example A continuous fractionating column is to be design to separate 30 Ib/h of a mixture of 40 percent benzene and 60 percent toluene into an overhead product containing 97 percent benzene and a bottom product containing 98 percent toluene. These percentages are by weight. A reflux ratio of 3.5 mol to 1 mol of product is to be used. The molal latent heats of benzene and toluene are 7,360 and 7,960 cal/mol, respectively. Benzene and toluene form an ideal system with a relative volatility of about 2.5; the equilibrium curve is shown in Figure below. The feed has a boiling point of 95 °C at a pressure of 1 atm.
