Answer / Pooja Jagtani

Tubular batteries and Automotive Plate batteries are both types of lead-acid batteries, but they differ in their construction, design, and performance characteristics. Here's a comparison:nn1) Construction:n- Tubular batteries have positive plates with tubes (or separators) between them to prevent short circuits.n- Automotive Plate batteries have positive plates without tubes, instead using a grid structure to separate the active material from one another.nn2) Design:n- Tubular batteries have a more compact design, making them better for deep cycling applications such as solar systems and backup power supply systems.n- Automotive Plate batteries are designed primarily for starting engines in vehicles, with a higher burst of current for short periods compared to tubular batteries.nn3) Performance:n- Tubular batteries have longer cycle life and lower self-discharge rates than automotive plate batteries.n- Automotive Plate batteries offer high cranking power for quick starting but may require more frequent maintenance.

Heat transfer: In a steady state one dimensional conduction with no heat generation, the differential equation is d / dx (k dT / dx) = 0. Prove that T(x) = ax b, where k, a and b are constants. (b) At x = 0, T = c and at x = L, T = d. Prove that T(x) = (d - c) x / L c for boundary conditions.

MY generator water cooler inlet line height - 11 mtr inlet water line height - 7 mtr water come into the line from overhead tank, O/H tank height - 20 mtr the first tapping in the inlet line is 2" line which down to 4 mtr level plateform., second tapping in inlet water line goes to a pump 6" line installed at 4 mtr level plateform, pump capacity 200m3/hr, head- 30 mtr, hp-40. the outlet of pump of 6" water line connected to a header of 6 mtr long of 6" line, on this header the six tapping are connected, 4 nos. 3" line goes to 11 mtr height water cooler the pressure of the line is 0.15 to 0.25 kg/cm2, 2" and 4" pipe line connected to a cooler at 4 mtrlevel plateform. my question is, at 11 mtr height level the quantity of water and flow is not sufficient for my cooler, the temp. of cooler is rises much more. you are requested to suggest the modification of pipe line/ pump for take more water flow and pressure (desired pressure is 1 kg/cm2)
