⦁ A secondary school has a population of 1500 students and 30 standard classrooms. Assuming a 5-day class week with solid waste pickups on Wednesday and Friday before class starts in the morning, determine the size of storage container required. Assuming waste is generated at a rate of 0.11 kg/cap. day plus 3.6 kg per room and that the density of uncompacted waste is 120 kg/m3. Standard container sizes (m3) are as follows: 1.5, 2.3, 3.0 and 4.6.

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false

The flow rate of air through a through a pipe is 0.02 m5/s. a pitot static tube is placed in the flow. the radius of the pitot static tube is 1 mm. assuming the flow to be steady and the air to be at 300k, calculate the difference in total and static pressure if the diameter of the pipe is: (a) d 0.1 m d 0.05 m (c) d 0.01 m
