Problem 4.079 SI A rigid tank whose volume is 3 m3, initially containing air at 1 bar, 295 K, is connected by a valve to a large

salantis [7]

Answer:

$Q_{cv} = -1007.86kJ$

Explanation:

Our values are,

State 1

$V=3m^3\\P_1=1bar\\T_1 = 295K$

We know moreover for the tables A-15 that

$u_1 = 210.49kJ/kg\\h_i = 295.17kJkg$

State 2

$P_2 =6bar\\T_2 = 296K\\T_f = 320K$

For tables we know at T=320K

$u_2 = 228.42kJ/kg$

We need to use the ideal gas equation to estimate the mass, so

$m_1 = \frac{p_1V}{RT_1}$

$m_1 = \frac{1bar*100kPa/1bar(3m^3)}{0.287kJ/kg.K(295k)}$

$m_1 = 3.54kg$

Using now for the final mass:

$m_2 = \frac{p_2V}{RT_2}$

$m_2 = \frac{1bar*100kPa/6bar(3m^3)}{0.287kJ/kg.K(320k)}$

$m_2 = 19.59kg$

We only need to apply a energy balance equation:

$Q_{cv}+m_ih_i = m_2u_2-m_1u_1$

$Q_{cv}=m_2u_2-m1_u_1-(m_2-m_1)h_i$

$Q_{cv} = (19.59)(228.42)-(3.54)(210.49)-(19.59-3.54)(295.17)$

$Q_{cv} = -1007.86kJ$

John read the first 114114114 pages of a novel, which was 333 pages less than \dfrac13 3 1 start fraction, 1, divided by, 3, e

sineoko [7]

Question:

John read the first 114 pages of a novel, which was 3 pages less than ⅓ of the novel. Write an equation to determine the total number of pages (P)

Answer:

114 = ⅓P - 3

Explanation:

Given

Number of pages read = 114

Total pages in novel = p

The relationship between the pages read by John and the total pages is analysed as follows:

3 less than ⅓ of total pages means:

⅓ of total pages - 3

Recall that P represents the total pages in the novel

So, the expression becomes

⅓ * P - 3

⅓P - 3

This means that the pages read by John is ⅓P - 3

This implies that the equation to determine the number of pages in the novel is

⅓P - 3 = 114

Solving further to get the actual number of pages;

Multiply both sides by 3

3(⅓P - 3) = 114 * 3

3 * ⅓P - 3 * 3 = 114 * 3

P - 9 = 342

Add 9 to both sides

P - 9 + 9 = 342 + 9

P = 351

Hence the number of pages is 351
