The guide vane angle of a reaction turbine (Francis type
make 20° with the tangent. The moving blade angle at entry is
120°. The external diameter of runner is 450 mm and the internal
diameter is 300 mm. Runner width at entry is 62.5mm and at exit
100mm. Calculate the blade angle at exit for radial discharge.

Compressor Selection: (Q1)
While a manufacturing cell is running, the calculated flow rate of air into a compressor is 40 SCFM.
Which compressor from this list should be selected?
A. A compressor that uses 80 SCFM
B. A compressor that uses 40 SCFM
C. A compressor that delivers 80 SCFM
D. A compressor that delivers 40 SCFM
SCFM Calculation: (Q1)
A pneumatic system running a manufacturing cell works on 80 psi and requires a flow rate of 10 CFM to operate.
A compressor must be selected to run the cell. Calculate the amount of air going into the compressor to run this cell. (Hint: This will be in SCFM)
Accurate to two decimals. Do not write the unit.

The cross-sectional area of the piston is 0.1 m2. Heat is now transferred to the water, causing part of it to evaporate and expand. When the volume reaches 0.26 m3, the piston reaches a linear spring whose spring constant is 100 kN/m. More heat is transferred to the water until the piston rises 20 cm more.

- A 4-m × 5-m × 7-m room is heated by the radiator of a steam-heating system. The steam radiator transfers heat at a rate of 10,000 kJ/h, and a 100-W fan is used to distribute the warm air in the room. The rate of heat loss from the room is estimated to be about 5000 kJ/h. If the initial temperature of the room air is 10°C, determine how long it will take for the air temperature to rise to 25°C. Assume constant specific heats at room temperature. The gas constant of air is R = 0.287 kPa·m3/kg·K (Table A-1). Also, cv = 0.718 kJ/kg·K for air at room temperature (Table A-2). Steam enters the radiator system through an inlet outside the room and leaves the system through an outlet on the same side of the room. The fan is labeled as W sub p w. The heat is given off by the whole system consisting of room, radiator and fan at the rate of 5000 kilojoules per hour.
