please solve the following problems and show your work. you may find this information helpful: T=293 degrees K (unless specified),R=0.0083 liter MPa/mole degree K, water g= 0.01 MPa/meter.
1.A cell in a leaf at the top of 20 meter tall tree has a dilute concentration 0.65 moles/liter and a turgor pressure of 0.40 MPa. calculate psi p, psi s, psi g and psi total relative to ground level.
psi is the water potential. psi s is solute potential. psi p is pressure potential. psi g is gravitaional potential
Please solve the following problems and show your work. You may find this information helpful T-2930K (unless specified), R = 0.0083 liter MPa/ mole 0K, pwaterg 0.01 MPa/meter 1. A cell in a leaf at the top of 20 meter tall tree has a solute concentration 0.65 moles/liter and a turgor pressure of 0.40 MPa. Calculate Wp s, Vg and Vtotal relative to ground level.Explanation / Answer
Given T = 293OK R = 0.0083 ltr MPa/mole degree k water g = 0.01 MPa/meter
Turgor pressure is 0.40 MPa, Ht of leaf is 20mtr, Dilute concentration 0.65 m/ltr
hydrostatic pressure equation p = gh
P = 0.0083 X 0.01 X 20
= 0.00166 N/m2
solute potentia s= c R T
= - 1 x 0.0083 x 293
= - 2.43 MPa
PSIA is a term that describes the absolute pressure in PSI, including the pressure of the atmosphere. Absolute pressure is also sometimes referred to as total pressure.
So the formula is PSIA = PSIG + 1 atm
= 0.00166 N/m2 + 1 atm
= 1.00166
