Problem 4. Let P be the orthogonal projection associated with a closed subspace S in a Hilbert space H, that is P is a linear operator such that
P(f) = f if f ∈ S and P(f) = 0 if f ∈ S⊥.
(a) Show that P2 = P and P∗ = P.
(b) Conversely, if P is any bounded operator satisfying P2 = P and P∗ = P, prove that P is the orthogonal projection for some closed subspace of H.
(c) Using P prove that if S is a closed subspace of a separable Hilbert space, then S is also a separable Hilbert space.

Consider a Rankine cycle with an ideal intermediate steam pickup, one of which is open and the other is closed feed water heaters. The steam enters the turbine at 12.5 MPa pressure and 550 degrees Celsius temperature and expands to 10 kPa condenser pressure. The steam separated from the turbine at 0.8 MPa pressure is sent to the closed feed water heater and the steam separated at 0.3 MPa pressure is sent to the open feed water heater. The feed water is heated to the condensing temperature of the steam leaving the turbine in the closed heater. The steam comes out of the closed heater as a saturated liquid, then the pressure is lowered into a valve and sent to the open feed water heater. Show the cycle in a T-s diagram with saturated liquid and saturated vapor curves.
a)
Water flow that must pass through the boiler for the production of 250 MW net power,
b)
Calculate the thermal efficiency of the cycle.

q1:In an open economy, a reduction in domestic demand has:
Select one:
a. a larger effect on output than in a closed economy and a positive effect on the trade balance.
b. a smaller effect on output than in a closed economy and a positive effect on the trade balance.
c. a smaller effect on output than in a closed economy and a negative effect on the trade balance.
d. a smaller effect on output than in a closed economy and a no effect on the trade balance.
e. a larger effect on output than in a closed economy and a negative effect on the trade balance.
Q2:
Policy makers can become concerned if the unemployment rate is too low because:
Select one:
a. output will increase.
b. stock prices will fall.
c. an exchange rate crisis might occur.
d. output will decrease.

Q3:
When the unemployment rate rises:
Select one:
a. the number of discouraged workers tends to fall.
b. the number of employed workers tends to rise.
c. the number of discouraged workers tends to remain constant.

The capital balance represents each partner’s initial capital
investment. Therefore, net income or net loss for 2020 has not been
closed to the partners’ capital accounts.
To record the division of net income for the year 2020 under each
of the following independent assumptions.
| 1. | Net income is $30,100. Income is shared 6:3:1. | |
|---|---|---|
| 2. | Net income is $40,500. Niensted and Bolen are given salary allowances of $14,500 and $10,400, respectively. The remainder is shared equally. | |
| 3. | Net income is $19,100. Each partner is allowed interest of 10% on beginning capital balances. Niensted is given a $14,180 salary allowance. The remainder is shared equally. |
(a)
Prepare a schedule showing the division of net income under assumption (3) above. (If an amount reduces the account balance then enter with a negative sign preceding the number e.g. -15,000 or parenthesis e.g. (15,000).)
