FAo(milli mol/h) 300 1000 3000 5000
CA,OUT (milli mol/l). 16 30 5 60. The reactor volume is 0.1 liter and the feed concentration at the temperature of the reactor is Cac =100 milli mol/l. Find the rate equation which satisfactorily represents the cracking reaction. in the above problem if we ignore density changes, what is the rate equation represents the reaction.

You are to select one project for development from the three options identified in task 1 using decision making software such as Mindgenius and devising a selection matrix. Your selection matrix may include parameters such as cost, availability of components, timescales, fit for purpose etc.
three options: ➢ Read Tooley and Dingle’s BTEC National Engineering (2nd Ed.) 2007, Unit 3 pp191-242
This is level 3 but a useful read.

Produce a Gantt Chart using Microsoft Project or another appropriate software to plan for the activities of the project duration. The GANTT chart should clearly show the time durations for each activity.
Produce a project design specification (PDS) using British Standard BS 7373 –3, PD 6112 which will highlight relevant information to be included in your project development.
At the exit of a toll gate with a single booth, vehicle arrive at random at a rate of 20 vehicles per minute. The service has an average rate of 22 vehicles per minute. Estimate the following:
(a) Average length of queue formed at the toll gate.
(b) Average waiting time of vehicles.
(c) Average time vehicles spent in the system.
Vehicles often travel city streets adjacent to parking lanes at 56 kph or faster. At his speed and setting detection through response-initiation time for an alert driver at 2 sec. and f = 0.50, how far must the driver be away from a suddenly opened car door to avoid striking it?
A cone of radius 2 cm and height 5 cm is lowered point first into a tall cylinder of radius 7 cm that is partially filled with water. Determine
how fast the depth of the water is changing at the moment when the cone is completely submerged if the cone is moving with a speed of
3 cm/s at that moment.
An open belt drive consists of two pulleys which are 5 m apart. The diameters of the larger pulley and smaller pulley are 2 m and 1 m respectively. The allowable maximum tension of the belt is 4 kN. The coefficient of friction between the belt and the pulley is 0.4 and the mass of the belt is 2kg/m length. Calculate:
3.1. The torque on the shafts when the larger pulley rotates at 300 RPM. (7)
3.2. The power transmitted. (3)
3.3. The speed in RPM at which maximum power can be transmitted. (5) 3.4. The maximum power that can be transmitted. (3)
A power of 4.5 kW must be transmitted from a pulley of an effective diameter of 0.25 m. The pulley is running at 1200 RPM. The angle of contact is 160° and the groove angle is 40°. The coefficient of friction is 0.2. If the allowable tension in each belt is 100 N, calculate the number of V-belts that will be required to transmit the power.
