nordsb [41]4 years ago

Answer:

a)P-v

Explanation:

Isobaric:

 Isobaric process is a process in which initial and final pressure will be same.This is also called constant pressure process.

If we take a process in which pressure is constant then there will be two possibility maybe this is compression process or maybe this is expansion pressure depending on the given condition.

In general only in P-v diagram ,isobaric processes are represented by straight lines.

If we take a saturated steam ,in which on T-s diagram pressure lines are represented by straight lines.

If we take the ideal gas Pv= mRT if we fix pressure then T-v digram will be linear diagram so we can say that here is also isobaric processes are represented by straight lines.

But from above most appropriate  answer will be a.

An adiabatic air compressor compresses 10 L/s of air at 120 kPa and 20 degree C to 1000 kPa and 300 degree C.
Oksana_A [137]

Answer:

work=281.4KJ/kg

Power=4Kw

Explanation:

Hi!

To solve follow the steps below!

1. Find the density of the air at the entrance using the equation for ideal gases

density=\frac{P}{RT}

where

P=pressure=120kPa

T=20C=293k

R= 0.287 kJ/(kg*K)= gas constant ideal for air

density=\frac{120}{(0.287)(293)}=1.43kg/m^3

2.find the mass flow by finding the product between the flow rate and the density

m=(density)(flow rate)

flow rate=10L/s=0.01m^3/s

m=(1.43kg/m^3)(0.01m^3/s)=0.0143kg/s

3. Please use the equation the first law of thermodynamics that states that the energy that enters is the same as the one that must come out, we infer the following equation, note = remember that power is the product of work and mass flow

Work

w=Cp(T1-T2)

Where

Cp= specific heat for air=1.005KJ/kgK

w=work

T1=inlet temperature=20C

T2=outlet temperature=300C

w=1.005(300-20)=281.4KJ/kg

Power

W=mw

W=(0.0143)(281.4KJ/kg)=4Kw

The function f determines the cost (in dollars) of a new Honda Accord in terms of the number of years t since 2000. That is, f (
lutik1710 [3]

Answer:

f(5)

Explanation:

Function notation  is  a precise way of giving information about a function without need for a lengthy written explanation. The most common function notation is f (x) which is interpreted as "f of x".

For the year 2005,

t = 2005 -2000

= 5

Using the function notation to represent the cost (in dollars) of a new Accord in 2005 is f(5)
