Answer:
Ensure that all material and energy inputs and outputs are as inherently safe and benign as possible. Minimize the depletion of natural resources. Prevent waste. Develop and apply engineering solutions while being cognizant of local geography, aspirations, and cultures.Green engineering is the design, commercialization, and use of processes and products that minimize pollution, promote sustainability, and protect human health without sacrificing economic viability and efficiency.The goal of environmental engineering is to ensure that societal development and the use of water, land and air resources are sustainable. This goal is achieved by managing these resources so that environmental pollution and degradation is minimized.

Answer:
5320.6 Pascal
Explanation:
Manometer is a pressure measuring device use to measure gas pressure .
Pressure difference in Manometer is a function of density,gravity and the height difference of the liquid.
Pressure difference = density x acceleration due to gravity x difference in height of liquid
Density of liquid = specific gravity of object x density of water.
Density of water = 997 kg/m^3
Specific gravity of liquid = 1.7
Density of liquid = 997 x 1.7 =1694.9kg/m^3
g= 9.81 m/s^2
h =320mm = 0.320m
Pressure difference = 1694.9 x 9.81 x 0.320 = 5320.6 Pascal
