Lift lbf = (Normal force lbf) x (cosine of angle of attack)
2.744 Newtons, or 0.62 lbf (pounds force)
"Psi" says the formula. The pound per square inch or, more accurately, pound-force per square inch - symbol: psi or lbf/in2 or lbf/in2 - is a unit of pressure or of stress based on avoirdupois units. It is the pressure resulting from a force of one pound-force applied to an area of one square inch. 1 pound per square inch = 6 894.75729 pascals Pascal (Pa) is the SI unit of pressure.

Volume = pi*r2*h = 95.03 cu ftAt a density of 5.81 pounds per cu ft the block would have a mass of 95.03*5.81 pounds.Using 32 ft/sec2 as gravitational acceleration, the weight is 93.05*5.81*32 pound-force =17,675 pound-force (lbf).
You must first determine the mass of the water, and you must also do some unit conversion. Since you know the volume of water, you must first determine its mass. One cubic foot of water weighs about 62.4 pounds (pound-force, lbf). But that's weight, not mass. What is the mass of 62.4 lbf of water? Since m = W/g, we get 62.3/32.2 = 1.93 slugs. (Note that the density of water varies with temperature, so the weight of a cubic foot of water will vary somewhat with temperature. It is densest at four degrees Celsius, but I chose to use the density of water at room temperature -- about 20 degrees C.) Miles per hour (mi/hr) is not a convenient unit, so convert to feet per second. One mi/hr = 1.47 ft/s, so 5 mi/hr = 7.33 ft/s. Kinetic Energy, Ek, is proportional to mass and the square of the velocity. It is given by the formula Ek = (1/2)mv2. Ek = (1/2)(1.93)(7.33)2 = 51.85 ft-lb (foot-pounds) = 70.3 joules.
If the lbf value was in cell B2, then the formula to convert it to Newton would be:=B2*4.44822162
F = W = ( 20 bags ) ( 50 lbf/bag ) ( 4.4482 N / lbf ) = 444.82 N <---[ Answer ]-------
You can not convert. Hertz is the frequency in an electrical AC system. lbf is what. If it is suppose to represent ft/lbs there is still no conversion between the two values.
The pound per square inch or, more accurately, pound-force per square inch (symbol: psior lbf/in2or lbf/in2or lbf/sq in or lbf/sq in) is a unit of pressure or of stress based on avoirdupois units. It is the pressure resulting from a force of one pound-force applied to an area of one square inch:
The unit for measure for force in the metric system is the Newton (kilogram-metre per second2), however for the English system it is the pound-force (lbf or lbf), which may be called a foot-pound.

pounds of force Foot pounds or torque. Measured with a torque wrench.
The Orca's bite force has not been measured because it's virtually impossible to measure the bite force of an aroused bull Orca under controlled conditions. Note that bite force is measured in lbf, not psi. Estimates range from 2000 lbf to 10,000 lbf. Measuring bite force in psi would require defining what surface you were measuring on - the tip of the tooth? across the entire jaw?
pound-force per feet2 (lbf/ft2)
I suppose that the correct spelling is foot pound force.

1 Newton = 0.2248 lbf = 102 gf, 10 Newtons = 1020 gram-force. 25 mm and one inch are almost the same, ratio = 25.4/25, so this will increase to 1036 gm-force per inch.
