Question Solved1 Answer The solubility of sodium bicarbonate in water is 11.1g NaHCO3/100 g H20 at 30.0°C and 16.4 g NaHCO3/100 g H20 at 60.0°C; the solubility varies approximately linearly with temperature over the range 5°C to 60°C. If a saturated solution at 60.0°C is cooled to 33.0°C, what percentage of the dissolved salt crystallizes?

Problem 2: A team of process engineers is tasked to design a geothermal power plant operating with low temperature brine (TA~ 135°C).

[4 Marks] ӘР Task 3 [Hand calculation] The partial derivatives and aV ¹ [¹ (SF),]₁ are called internal pres- sure and thermal pressure, respectively. For a gas that behaves as a van der Waals fluid, derive expressions for both terms. Also, for gaseous ammonia at 2.5 bar and 5°C, calculate both terms, internal pressure and thermal pressure. For your calculations, consider that Pc = 113.57 bar, T = 405.7 K and w= 0.253. [10 Marks]

NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part To place a communications satellite into a geosynchronous orbit at an altitude of 22,240 mi above the surface of the earth, the satellite is first released from a space shuttle, which is in a circular orbit at an altitude of 185 mi, and is then propelled by an upper-stage booster to its final altitude. As the satellite passes through A, the booster's motor is fired to insert the satellite into an elliptic transfer orbit. The booster is again fired at Bto insert the satellite into a geosynchronous orbit. The second firing increases the speed of the satellite by 4830 ft/s. INS Rani Determine the increase in speed resulting from the first firing at A. The increase in speed resulting from the first firing at Ais ft/s.

PLEASE IN C++ 1) Chuck-a-luck - 15 pts Chuck-a-luck is a simple dice game for gamblers. You can play it in some Vegas casinos. To play, the gambler first places a wager, W. The gambler then picks any number from 16. Let n represent the gambler's number. Next, the gamber rolls three six-sided dice. If none of the rolls equals n then the gambler loses W. If
