1. What gauge pressure in Pa must a pump produce in order to pump water from the bottom of Grand Canyon (730 m elevation) to the Indian gardens (1370 m)?

2. Calculate the pressure at the bottom of the container with 1.2 m high layer of oil (SG=0.82), 0.5 m layer of water and 0.3 m layer of mercury (SG=13.6)

3. A cube having a side 8 cm in length has a density of 900 kg/m³. What is the mass and unit weight of the cube?

4. Georgie is trying to float his toy boat on water during one rainy day. If it weighs 130 N and has a density of 9 g/cm³, what is the total volume of the toy and the buoyant force exerted on it?

A particle is moving along a curved path, at a certain instant when the slope of the path is 0.75, ax= 6fps and ay= 10fps. Compute the values of tangential acceleration at this instant and sketch how the path of the particle curves.

Considering you have an ATV. Given the mass of the vehicle with the driver is
220kg and it moves with an average speed of 40km/h. It decelerates with 0.7g.
Can you find the coefficient of friction with the given data?

A motor car with total weight of 40 kN and wheelbase of 2.75m with CG of
0.85m above the ground and 1.15m behind the front axle. If coefficient of
adhesion is 0.6, Compute the maximum possible acceleration and the normal
reactions when the vehicle is –

ii) Driven on rear wheels only iii) Derive the formula used for the above.

A petrol engine works on an air standard Otto cycle. The pressure and temperature of the air at the beginning of the cycle are a bar and 15°C. The compression ratio is 8 and heat supplied per kg of air is limited to 2000 kJ. Find the following : () The air standard efficiency of the cycle (i) The mean effective pressure.

an air standard Otto cycle engine, the temperature at the end of compres- sion stroke is 650 K and the max cycle temperature is 2400 K. If the engine delivers 700 kJ/kg of net work, find the thermal efficiency and compression ratio of the engine.

In a diesel cycle, the compression ratio is 18 and cut-off ratio is 1.6. The pressure at the beginning of compression is 1 bar. Determine the mean effective pressure. Assume y = 1.4.
