Answer:
Given
inlet Pga =40kpa = 40000pa
Patm=1.01bar = 1.01 x 100000pa =101000pa
exit Pab= 6.5 (inlet Pab)
But generally, Pab = Patm + Pga
1. the absolute pressure of the gas at the inlet, inlet Pab?
inlet Pab = Patm + inlet Pga
= 101000pa + 40000pa = 141kpa
the absolute pressure of the gas at the inlet, inlet Pab = 141kpa
2. the gage pressure of the gas at the exit? exit Pga?
exit Pab = Patm + exit Pga
exit Pga = exit Pab - Patm
= (6.5 x 141kpa) - 101kpa
= 815.5kpa
the gage pressure of the gas at the exit exit Pga=815.5kpa

The rainfall run off model HEC-HMS is combined with river routing model. They are used for simulating the rainfall process.
Explanation:
The HEC - HMS rainfall model is used for simulating the rainfall runoff process. In this study the soil conservation service and curve number method is used to calculate the sub basin loss in basin module.
It provides various options for providing the rainfall distributions in the basin. It has the control specification module used to control the time interval for the simulations.
The one dimensional continuity equation is
бA / бT + бQ / бx= 0
Answer:
metals, composite, ceramics and polymers.
Explanation:
The four categories of engineering materials used in manufacturing are metals, composite, ceramics and polymers.
i) Metals: Metals are solids made up of atoms held by matrix of electrons. They are good conductors of heat and electricity, ductile and strong.
ii) Composite: This is a combination of two or more materials. They have high strength to weight ratio, stiff, low conductivity. E.g are wood, concrete.
iii) Ceramics: They are inorganic, non-metallic crystalline compounds with high hardness and strength as well as poor conductors of electricity and heat.
iv) Polymers: They have low weight and are poor conductors of electricity and heat
