Blockpy: #35.2) compose some functions there are three functions below that filter, map, and sum lists: remove_xs consumes a list of strings and removes any "x"s map_strs_to_ints consumes a list of strings and produces a list of integers summate consumes a list of integers and adds all the numbers together compose the functions in a new function named total_values such that they are applied correctly. this function should consume a list of strings (numbers and "x"s) and produces an integer representing the total ignoring the "x"s. you do not need to modify the existing functions.

Liquid flows at steady state at a rate of 2 lb/'s through a pump, which operates to raise the elevation of the liquid 100 ft from control volume inlet to exit. the liquid specific enthalpy at the inlet is 40.09 btu/lb and at the exit is 40.94 btub. the pump requires 3 btu/s of power to operate. if kinetic energy effects are negligible and gravitational acceleration is 32.174 tt/s, the heat transfer rate associated with this steady state process is most closely 1)-2,02 btu/s from the liquid to the surroundings 2)-3.98 btu/s from the surroundings to the liquid. 3)-4.96 btu/s from the surroundings to the liquid. 4)-1.04 btu/s from the liquid to the surroundings.
