4. write assignment statements that perform the following operation with the variables a, b, and c:

(a) adds 2 to a and stores the result in b.
(b) multiplies b by 4 and stores the result in a.
(c) divides a by 3.14 and stores the result in b.
(d) subtracts 8 from b and stores the result in a.
(e) stores the value 27 in a.
(f) stores the character ‘k’ in c.
(g) store the ascii code for ‘b’ in c.

Steam enters a turbine at steady state at 2 mpa, 360°c with a velocity of 100 m/s. saturated vapor exits at 0.1 mpa and a velocity of 50 m/s. the elevation of the inlet is 3 m higher than at the exit. the mass flow rate of the steam is 15 kg/s, and the power developed is 7 mw. let g 9.81 m/s^2. determine: a)-the area at the inlet, in m^2 b)-the rate of heat transfer between the turbine and surroundings, in kw c)-draw a p-v diagram for this process.
