What is the specific enthalpy for steam at 17.5 bar and 443 °C? show the steps for double interpolation to arrive at your answer
A cylinder that contains 0.064 kg of carbon dioxide (with molar mass 44 kg/kmol), occupying a volume of 0.025 m3 at 1.1 bar, is compressed reversibly until the pressure is 1.9 bar. Calculate the final temperature, the work done on the C02, and the heat supplied when the process is isothermal
A cylinder that contains 7kg of CO2 with molar mass 44kg/kmol, occupying a volume of 0.025 m^3 at 1.1 bar, is compressed reversibly until the pressure is 230pa. Calculate final temperature, work done on CO2, heat supplied when the process is isothermal.

Explain the issues that influence whether a design proposal should be developed into a final solution suitable for manufacture. Write at least 600 words and include a flow chart showing how the decision-making process works when a company design review takes place. You must address the following points:
How might manufacturing constraints affect the decision-making?
What are the financial implications attached to making design decisions?
How does legislation affect making design decisions?
In a crank and slotted lever quick return motion mechanism, the distance between the fixed
centres O and C is 200 mm. The driving crank CP is 75 mm long. The pin Q on the slotted lever,
360 mm from the fulcrum O, is connected by a link QR 100 mm long, to a pin R on the ram. The
line of stroke of R is perpendicular to OC and intersects OC produced at a point 150 mm from C.
Determine the ratio of times taken on the cutting and return strokes.
A shaft composed and set up with different materials is shown with a torque applied. Each of the parts has their own equivalent torsional spring constant. How are these parts connected?
A three step shaft is connected as shown. Torque will be applied on the location provided. Considering each of the segments, 1,2, and 3, to have their own equivalent torsional spring constant, how are these torsional spring constants connected?
A solid shaft is to transmit 800kw at 300rpm. if the shaft is not to twist more than 1 degree on a length of 20 diameters and the shear stress is not to exceed 50mn/m2 with a modulus of rigidity of 90gn/m2, design the shaft by determining a suitable diameter
Two coaxial solid shafts of diameter 120mm each are to be connected by a flanged coupling using M12 X 1.5 steel bolts equally spaced around a 320mm pitch circle diameter of the flange. The flanges have thickness of 15mm each and must be welded to the shafts. The coupling must deliver 500kW of power at 400rpm.If the allowable shear stress and bearing pressure are 90N/mm2 and 65N/mmw respectively,on the basis of power being delivered,design the coupling by; Determine (a) Number of bolts required (b) size of the weld (c) efficiency of the coupling
