Consider rider on a typical bicycle pedalling up a hill. specifically, the case when the cyclist is using their body weight alone to apply the pedalling force. draw a diagram of the situation that you can use to analyse the system and answer the following questions: a)-does the mass of the rider affect the acceleration of the bike (and rider) up the hill? b)-is there an optimum ratio from pedal crank radius to rear wheel (including the chain drive ratio) that will maximise the acceleration? c)-is there a maximum angle that the bike and rider could ride up? d)-how does the angle of the pedal affect the acceleration (if at all)? e)-what coefficient of the friction is needed between the tyre and the wheel to ensure no slipping? for this question ignore the following: frictional losses within the bike . air resistance

8.29 two streams containing pyridine and acetic acid at 25°c are mixed and fed into a heat exchanger. due to the heat-of-mixing effect, it is desired to reduce the temperature after mixing to 25°c using a stream of chilled ethylene glycol as indicated in the diagram. calculate the mass flow rate of ethylene glycol needed. the heat capacity of ethylene glycol at these conditions is approximately 2.8 kj/(kg k), and the enthalpy change of mixing (δmixh) is given below.
