1. A surge is moving at 9 f t/s into a basin of depth 1.4 f t where the speed is zero. Find the water depth behind the surge and the drift velocity behind the surge (that is, the velocity downstream of the surge in a stationary frame of reference).
2. A river of depth 2 m flows downstream at 1 m/s. A surge of depth H moves up the river at 5 m/s relative to a stationary observer on the bank of the river. Find H.
the Redlich-Kwong equation to calculate the value of the pressure of one mole of ethane at 400.0K confined to a volume of 83.26 cm^3. The experimental value is 400 bar.
Referring to Figure, describe all the phase changes that would occur in each of the following cases: Water vapor originally at 0.005 atm and -0.5 °C is slowly compressed at constant temperature until the final pressure is 20 atm.
Biology timed quiz! Can you help me? It is short but important (aprox 30 min) The emphasis is on the human anatomy.
An average human adult takes about 15breaths per min and exhales 23ml of co2 with each breath. If your trapped in a cave with pressure .963atm and 11C and your only source of oxygen is a breathing device containing 1kg of KO2 , how long do you hav..
If the pressure of "wet" hydrogen is assumed to equal atmospheric pressure and the volume is recorded, will the calculated moles of hydrogen gas be too high or too low?
Calculate the pH of 1.00 L of a buffer that is 0.140 M HNO2 and 0.180 M NaNO2. What is the pH of the same buffer after the addition of 1.00 mL of 12.0 M. HCl. (pKa of HNO2 = 3.40). What is the pH of the Original buffer and after HCl is added?
