Question 1 a) Initially, the wheel was filled with Nitrogen at temperature of 20°C and a pressure gage of 200 kPa. The volume of the wheel was considered to remain unchanged and equals to 18 L. i) Obtain the gage pressure in the wheel when the Nitrogen temperature in the wheel rises to 45°C. ii) Obtain the mass of Nitrogen that must be removed in order to restore pressure to its original value at this new temperature. b) Calculate the gage pressure at points A, B, C and D. Take air density as 1.21 kg/m.

The present pumping rate of crude oil through the Alaska Pipeline with an ID of 39 in is 550,000 barrels per day (1 barrel is 42 U. S. gallons). For crude oil at 60ºC, take ρ = 860 kg/m3 and μ ≈ 0.004 kg/m·s. What would be the maximum rate if the flow were constrained to be laminar? Take π = 22/7. Answer is asking for maximum flow rate for barrels per day

A water from Agno River is pumped using a submerged pump at an efficiency of 78% that is discharged to aswimming pool in Itogon which has a free surface of 30 m above the Agno River water level. The pipe that wasused has a diameter of 7 cm on the suction line and 5 cm on the discharge line from the pump. If the powerrequirement of the pump is 5 kW assuming that the elevation difference between the pump inlet and outletand the effect of the kinetic energy correction factors are negligible, calculate for the followinga) Power requirement by the pump in kWb) Pressure difference across the pumpc) Pumping cost/day(24 hour) if the electricity cost is ₱2.00/kW-hr
