(2013) have proposed an alternative equation of state, based on the reduced saturation temperature (T, = T/Terit) only, as followsIn(vg) = a + b[ln (1/T,)]04 + c/T² + d/T + e/TValues for a -e are given belowA = -7.75883B = 3.23753C = 2.05755D=-0.06052E = 0.00529The aim of this exercise is to validate or otherwise the two methods using a data set taken from the Rogers and Mayhew property tables used in this module.This data is given below:In [1]; import numpy as npdata = np.array([[0.5,81.3,3.239],P [bar] Tat [C] ug [m³/kg]0.581.3199.61020[1,99.6,1.694],[10,179.9,0.1944),[20,212.4,0,09957),[40,250.3,0.04977),40100150180200220The code below can be used to import the Rogers and Mayhew table.

Implement a function that finds the number of values that are less than 0 and the number of values greater than 0 stored in an array of integers. Assume the array is the partially filled array from the previous question, and uses 0 to indicate the end of values stored in it. (18 pts) Note: the results should be passed back to the caller, not directly displayed in the function. Also note, as the following code template requires, the function’s return type is void. Please finish the function header, and function implementation. Hint.. In the beginning, set the lessThan and greaterThan values to be 0. Then as you scan through the array elements one by one, compare the next array element with 0. If the element is greater, update your greaterThan count; otherwise, if the element is less, update the lessThan count, otherwise do nothing. Continue until you see the value 0.
