Question

Write a function print_power_outputs(dam_records) that takes a list of (name, flow, head, efficiency) tuples for hydro-dams
and prints the power output for each dam in the format shown below. The power output should be printed to 2 decimal
places.
The power output for a hyrdo-dam is calculate using the following formula:
Power = 9.81 x flow x head x efficiency
Where:
• 9.81 is the gravitational constant in m/s2
• power is in Watts
• flow is the rate of flow through the turbines, in m/s
• head is the net effective head in metres (basically, the height/depth of the water in the dam)
efficiency is the overall efficiency of the system as a value between 0 and 1 (e.g. 90% efficiency would be 0.9)
For example:
T.
Result
Test
[('Dammy', 3, 10, 0.875),
The Dammy dam has a power output of 257.51 Watts.
dams
('Damuel', 4, 8, 0.75),
The Damuel dam has a power output of 235.44 Watts.
('Damielle', 4, 8, 0.75)] The Damielle dam has a power output of 235.44 Watts.

In Python code: Write a function to convert a integer to hexidecimal. Do not use the Python hex function (i.e. hexnumber = hex(number)) to convert the number, instead write your own unique version (i.e. MYHEX: hexnumber = MYHEX(number)). Your function should not use any Python functions like hex, dec, oct, bin or any other Python functions or modules. Functions, like Python ORD, can be used to convert a string to a integer.

Write the function truck_adjustment_factor(truck_proportion, terrain_type) that takes the proportion of trucks using the motorway and the terrain type as inputs and returns the adjustment factor that is used for calculating the highway capacity. The adjustment factor is calculated according to the following formula: adju stment factor = tprupurtime x(furtor-1) Where proportion is the proportion of trucks and the factor is the car equivalent factor for the given terrain. You should be calling your car_equivalent_factor function to get the factor - don't reinvent the wheel! For example, for rolling terrain and a truck proportion equal to 0.12: adjustment factor = 1/(1 + 0.12 x (4.0 - 1)) = 0.735 Notes: You should include (and call/use) your car_equivalent_factor function in your answer o In general, you should paste in your whole module so far in each question as later functions will call earlier functions. • You can assume the function will always be called with one of the three valid…
