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
(b)
Interpretation:
The three assumptions made to solve Part (a) and their impact on solution is to be stated.
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.

A burning dump emits an estimated 1.5 kg/min of nitrogen dioxide (NO2 ). On a partlycloudy morning with a 2.5 m/s wind and temperature of 18°C, what is the concentrationof NO2 at a distance of 3.0 km directly downwind of the dump? Does this exceed theshort-term exposure limit for NO2 ? State your assumptions.

are given below. The temperature was constant at 500K and the total pressure was constant at
830 kPa. The entering number of moles of species A is 100 mol. Calculate the time necessary to
achieve 80% conversion.
